Best Video Setting for Smooth Video?

Anyone know what is the best setting for smooth video playback when viewing in Touch Pro 2?
I have download the Transformers 2 Trailer in FLV format and playback on my Touch Pro 2 but it seems to be laggy.
Anyone can advise me whether it is the video format problem or the phone memory problem as I have installed many applications.

Can only get on youtube through my Rhodium at work but isn't that video HD?
It's got a pretty fast processor for a phone but it's still only 533MHz, it can't playback HD content!

I've seen a couple of DivX movies (700MB each) on my TP2 and I have no lag issues...
In fact, I did had that, but back then I was using the player supplied with DivX codecs for Windows Mobile. Once I started using Core Player, the "lag" was gone.
I'll try that YouTube HD video in FLV format and get back to you.
BTW, what player are you using?

Yea i have no issues at all with any video format with coreplayer with the exception of mkvs.

I am also using Core Player for playing back the above FLV format file.

Sorry for the delay guys, but during my video speed testing , I found that although Core Player is supposed to play MP4 files (so they say), on my TP2 Core Player says "Player: Video codec (AVC aka H.264) not supported by the player!". So it seems that I have no H.264 codecs installed, which is strange because the H.264 codec is quite common on DivX. Well, I guess the movies I've been playing were not H.264 encoded.
This happened because I downloaded (without converting) both Transformers 2 trailers (LowRes and HD) from that link. The LowRes version came in FLV format (4MB), and the HD is a 33MB MP4 file. The FLV plays flawlessly without hiccups or delays.
I'm still searching for H.264 codecs for Windows Mobile, and will report back to this topic after installing and testing the video.

The HTC player will playback mp4's encoded with H.264, so long as they're Standard Definition with stereo audio.

I have download the same file again by copying the Videoplayback file in FLV Format from Internet Explorer Temporary Files Folder, file size is 12.2MB instead of 4MB.
How you can get 4MB and how you download the Low Res file? The playback is a bit jerky and not so smooth but after comparing the original one in YouTube, it is also a bit jerky and not smooth so there is nothing wrong with the Touch Pro 2 Playback as the problem lies on the source itself.

What you wanna do is get Coreplayer.
Encode your videos into Divx with vertical res. of 720 or under and keep the bitrate under 1500kb/s.
Great image quality with approx 112% playback speed.

I have used Coreplayer for playback.
Tried encoding "The Black Knight" Movie in the below format :
1) Width x Height (704 x 296)
2) Bit Rate (64kbs)
3) Audio Format (Lame MP3)
4) Frame Rate (23 frames/second)
5) Data Rate (1031 kbs)
6) video Sample Size (24 bit)
7) Video Compression (XVID)
There is some portion of the playback jerky and not smooth, any problem with the above settings?

You could try downloading that little encoding program.
It encodes your files into the perfect format for HTC Album. The user interface of the program is very easy and it encodes your files so that they play with full resolution and a good bitrate. Hope I could have been of help. All credit goes to it's creator.

I used a Firefox addon that "strips" the contents out of the pages (videos, sounds, SWF, ...). It can also be used to convert to other video formats while downloading, but I didn't use this feature as I wanted to test with the real deal.
I double-checked just now, and the smaller file (LowRes) is 4.76MB and it's fully functional and it plays 'till the end. The HD is 33,9MB. Perhaps there's a different file version when you stream directly from the internet... it doesn't make much sense, but I'm just guessing.
I didn't had time to continue searching for the right codecs yet. But I'll give it a go tomorrow. I'm sure I was not the 1st to experience this "issue" and the codecs "should" exist somewhere... so I hope.

Thanks for your recommendation and I recode the video again, it is much smoother playing over the WMP.
Will use this program to encode future DVD or Video for playback in my Touch Pro 2.

[Q] 720p video playback issue

Hello,
I'm having some problems about playing 720p videos from HTC Desire Z. It plays some 720p videos smoothly which are recorded by itself (also there is a fps problem in there, some are about 19fps).
I wonder which {container, codec} we should use to play 720p videos smooth. I tried with several media players like Vplayer, Moboplayer, Rockplayer and Android's default media player.
I tried some files. Here their properties:
Container: MKV
Video Codec: H264
Audio Codec: AC3
Overall Bitrate: ~4.5Mbps
Length: 71min
Size: 2.2GB
This was a concert video.
--
Container: MKV
Video Codec: H264
Audio Codec: AC3
Overall Bitrate: ~4.5Mbps
Length: 40min
Size: 1.1GB
This was a tv show.
Rockplayer can play this videos but not smooth enough. It freezes for 5-10 milliseconds at every 1-2 seconds.
Using stock 2.3.3 ROM and stock SD Card.
Phone can play 480p videos smoothly but I think it can play 720p videos since it can record 720p videos.
Thanks in advance.

The DZ isn't actually powerful enough to play 720p videos from an external source. I can barely play 480p AVI smoothly. MKV and MP4 are a total lost cause for me. Haven't tried after I installed Virtuous 2.0 and had it OC'd to 1.5GHz though.

As far as I know, DZ has hardware decoding for 720p videos. So it can play 720p videos and DZ records with 8mbps and encodes with h264 and its container is 3gp. Only difference is container. Maybe changing container will fix this but I tried with avi, mkv. Maybe I should try with 3gp container.
Anyone tried?

Tried with its trial version but it says "sorry, this video can not be played" when i try to play video which I mentioned at my first post (tv show one) and also another video which is a mp4 video.
DicePlayer can not play any video in the phone

I use Rock Player Lite and it can play MP4 vids properly. Granted, I just OC'd my DZ to 1.5GHz, and an MP4 file encoded in h.264 with an average bitrate of 1.5kbps plays flawlessly. At stock speeds the audio goes out of sync and artefacts get introduced. Haven't tried MKV files since I OC'd yet though. Software decoding in RPL.
Hardware decode basically is the same as the default media player, software decoding takes up more CPU resources, but is able to play more formats and containers.

I haven't found any way to reliably open mkv container on desire z. MX video player by far does the best job (and yes, I've used other players like rockplayer, dice player, etc) but it still plays 720p mkv h264 slightly choppy. 720p h264 mp4 plays fine with software and hardware decoder, while 720 avi xvid can play smoothly on a small overclock.
I try to avoid 720 anyway because the difference between 720 and 480 on a 3.7inch screen is barely visible to me lol

Exactly lol. As long as it can play 480 on the DZ it's more than fine by me. 720p on a 480x800 screen... ~_~
MX Video Player.. Never heard of it. Gonna search and try that out. How does it compare to Rock Player?

i really liked rockplayer for a long time until i found out mx player had software codecs tweaked for ARMv7. Check it out on the market, its free anyway lol

I tried mx player but still there is the same problem.
I also tried to change the container to mp4. PC plays well but when I try to play on phone, video is smooth but there is no sound and audio codec is ac3. Maybe the problem is here.
I tried with rockplayer using software decoding, there is sound but laggy video.

Try MX with SW. Works fine on any container and format so far for me.

The trick is to use video in the correct settings for the hardware decoder. If you do that then it won't matter if it's in mkv or mp4.
For the video portion, use baseline profile h.264 with the maximum bitrate (VBV) capped at 8mbps up to 720p
For audio, use AAC-LC in stereo.

I think so. But there is a problem when playing MKV files. There is problem after I changed container to mp4, though.
But the audio codecs of videos which I tried are not AAC. Maybe this causes the problem.
I don't know, how hard can it be to play videos which have AAC audios.

Use Handbrake to encode and it'll be easy to specify AAC for audio. You can use the iphone profile for encoding.

Hi again,
I've solved my problem. I use dice player which plays 720p mkv videos (even with ac3 audio codec).
I wrote here dice player can't play any video in the phone. That was a hardware decoding problem, I think. When I try to play an unsupported video format with hardware decoding, hardware decoding crashes and unable to play videos as it should be.
So, after that if I restart the phone hardware decoding comes back and plays videos perfectly.
Is this a common issue? If it is not should I do a factory reset to my phone?

To be honest, with our default 800*480 screen, we would not be able to take advantage of 720p quality as 720p is 1280*720 (Unless we stream it to a HDTV or Monitor). Re-encoding it to 800*450 is wiser to conserve file size as well
found this recommended settings at afterdawn for Handbrake or MEGUI. Tried it with rockplayer hardware decoding and it is smooth i used mp4 format

[Q] Playing MKV files on phone

I bought an Xperia SL recently, solely for the purpose of watching videos. Most of the videos I download have the mkv extension and are 720 - 1080p. I downloadedcl MX Player along with its codec and started the video. The video only works on software decoding and desyncs + lags like hell. I dont want to convert it, as I want to download and watch straight away.
Could you help me out? (except saying that download in some other format)

The stock movies app works for me
Posted by Xperia™ Ion via xda-premium

Try BS Player. Played everything I threw at it with HW decoding.

The stock player just shows a black screen. As does mx player on hardware decoding.

Try MX Player Free or Pro version. Make sure you use the latest one. It played every file i tried.
While playing change the decoding to HW/SW depending on your need. HW is set by default.
Search for MX player in Google Play.

stock movie app is working for me too on .mkv file.

Please use our Q&A section for all questions. See XDA rule #15

@entermetallica:
Same answer as allways.
MKV is no videoformat, it's a container that can consist of audio and video in different formats.
Download the video on a PC, use VLC to view it and then goto Extra/Codec Info.
Post what's there, esp. Mangas are known to use way out of spec coding parameters.

or...
Use VLC like a man

DicePlayer is also a good option.

mx player
try SW, HW and HW+ modes

I use the lastest version of both BSPlayer and MX Player Pro(16bit).
Both play .mkv 720p 6-channel audio movies using HW acceleration on my XPERIA LT26i. I haven't tried 1080p .mkv
BSPlayer uses it's own HW engine and defaults to HW encoding.
MX Player Pro needs to have the HW options enabled in the application settings first.
My XPERIA X10i Adreno 200 running GB 2.3.3(sony fw) uses HW encoding in 720p .mkv movies.. so I'm very sure it's got to work on an XPERIA LT26i Adreno 220 ICS 4.0.4(sony fw)
What firmware are you running???
If you've installed some sort of JB fw ... then true, you may lose HW encoding if the Adreno 220 drivers are not HW enabled in a given firmware not supplied by Sony/Qualcomm.
I use Handbrake on Win7 to encode/decode videos which have default Android and/or HD video settings.

Yup, you've hit the nail on the head. Most likely a codec that's not supported, MKV container is supported by the stock video players and most players form the Google Play market. If we could have a list of codecs that are supported by our Xperia S/SL that would maybe help clearify things.

Using H264 video codec and ACC or AC3 audio in my .mkv container and that's fine with XPERIA S and gives HW acceleration.

Or will it be done by flashing a custom rom(may be cm10)

+1. You can even boost the volume level to upto 30 if you use HW+ decoding, works amazing on AC3/DTS audio

serviio and diceplayer. Makes a great DNLC network that can stream any file to your Nexus. As for playing it on the nexus, I personally dont like putting movie files on mine since the memory gets used up rather quickly.

MX Player and the VLC Beta both work fine with .mkvs for me. I've even played some pretty hefty 1080p files with no issues.

you don't need to do anything. just open the file with MX player, be player or similar. sorry I'm not understanding why this is an issue for you

You can use HW decoding for video in players such as MX Player but you can't do audio HW decoding for some codecs since Dolby is suing everybody for supporting their formats without permission and is also refusing to license them.

MX Player works great in HW+ mode. I have had no problem with normal HD mkv files or 10 bit anime mkv

Actually you can, custom codec option in mx player Worked wonders for me, there's threads about this. Stock rom, locked.

Yes, it can for both 8-bits 720p and 1080p, but 10-bits sorry, can't....

Can anyone point me to the right codec to download? All videos I try are using S/W instead of H/W in MxPlayer (except MP4). WMV and MKV are playing in S/W. Thanks a bunch

ya, where do i download the latest HW codecs? my s/w works fine but HW mode doesnt work too well in mxplayer pro/ lags and stutters

Some education is needed
MKV is not a codec, it's a container format much like DVD .... The problem is not the MKV container but what it contains. Generally the biggest problems are MKV's made from US OTA (Over the air) and cable TV recordings which all have the audio in AC3 format and usually in Dolby encoding. (And as someone mentioned Dolby doesn't like it when they don't get their Cut, even if the software is free and no one is actually profiting from it except the Consumer)
I've recorded and archived several TV series since 2006 and some of my first MKV's kept the AC3 audio format (but converted the video to h.264) because I was having sound sync problems (Not sure if it was an x264 or the cable company's fault but the issue eventually went away) and for those I have to use software decoding for the audio but the video is still hardware accel .... The ones I've made in the last 3-4 years have the audio converted to AAC format and those have full hardware accel video and audio and play flawlessly and effortlessly even on my lowly Rockchip dual core TV Stick (720p and in the process of being embedded in a Motorola Lapdock)
Point being it's not the MKV container that is the problem, what counts is the formats it contains .... And in the case of us North Americans we need to convert the audio (AAC is the best bet IMO) so you may as well convert the video (Much of it is interlaced and that's another issue conversion fixes, Handbrakes default Decomb filter does it well) .... For that I would recommend x264 and Handbrake (x264 is included in Handbrake) which should not only take care of compatibility issues it also makes for a smaller file (Better transfer/streaming over wifi) without any loss of playback quality .... Also I would recommend stripping off any extra audio feeds (Languages) if you aren't going to use them, ditto for subtitles ... In other words keep it simple and convert to formats with known/best compatibility

SPAM.

what about the mpeg2 decode ,not h/w decode?

no hardware acceleration for 1080i dvb-s2 recordings or streams
My nexus 7 with stock Rom plays 1080p h264 content in MKV containers flawlessly with h/w acceleration with various players. Except for either streams or recordings from my tvheadend server. If they are 1080i (no German station broadcasts in 1080p) none of the players gets h/w working. SD and 720p do work though. The only difference I can see between my recorded files and the ones that do play is that the recordings have 25 fps whereas the other mkvs have about 24.
In the attachments there are two screenshots of two mkvs' properties. The 25 fps one is the one that won't work.
Anyone's got an idea? Thanks

from what i know,snapdragon still don't support 10bit decoding perfectly,thats why u can't use hw+ mode for 10bit video.
When I tried with my HTC One X,it can play 10bit video in hw+ mode though.Its likely for now Tegra and Exynos only support 10bit decoding in hw+ mode,even not perfectly.

Hi,
i have problems with 1080p MKV and MP4 playback.
When i playback a movie with 1080p and Hardware Decoding, I get terrible blocking and freezing (strainge colours, green Pixel and so on).
I tested with MX-Player (H/W+), VLC Player, Plex and XBMC. The result is always the same.
When i use the same file in ts oder m2ts - Format, then everything is ok.
So i tested to create the mkv and mp4 File with different Tools: mkvmerge, ffmpeg, makemkv, mp4box and so on..
Always Errors and terrible playback.
Is there a trick or can the device handle HD only in *.ts without Errors???

I'm able to play 1080p mkv files and mp4 files without issue. I actually download a lot of 1080p movie trailer in mp4 format to my tablet. However, I normally use Archos Video player or BS player though as the hardware acceleration appears to be better on them than other video players I've tried.

I use mx player and never have an issue, have you tried the software codec for mx?

Archos has the best Performance. you only see sometimes litte stuttering. But the PGS-Subtitles are not shown -((
BS-Player has Picture -Errors
MX-Player in S/W and H/W Looks ok, but not enough Performance for full framerate Decoding.H/W+ Decoder has enogh Performance, but the same Errors in the Picture like BS-Player, Plex, XBMC abd so on.
I don't understand why... the Problem ist not all movies... and this are not the movies withe the highets Bitrate. convert to ts looks good.
I put a short sample online.. mail me, if you are interessed to verify and help... I can not post the link here.. (new user board-rule)

Maybe your files (muvies) are stored in ExtStorage (microSD).
Have you check your microSD card speed?

Try Dice Player its one of the best players out there, but for DTS audio you need "libffmpeg.so" from the attachment below.
Other than that try a test sample with video stream only and see if it plays fine, if it does then mux in the other streams one at a time until the problem returns.

10 bits encoding maybe?
