[Q] Playing videos on WildfireS

I have heard WildfireS can play Xvid and Divx movies (.avi files)
Is this true ?

Yes it can but only software decoding mode (I watch them with moboplayer which install a codec pack for this).

Hello, I find moboplayer leggy and sound and video out of sync. Can you share your experience.
Is there a way to play video on this phone without problems?

Hi,
what are the properties of the file you are trying to play? what is the codec (divx, xvid, H264...) and the container/file format (avi, wmv, mkv, mp4....)? And also te resolution of the video file.
Real fact:
1. one StarTrek TNG episode (350MB file size); container: avi; resolution: 512x384, codec DIV3 (DivX 3) it plays very smooth with mobo player in hardware decode mode
2. one The Big Bang episode (175MB size); container avi; resolution: 624x352, codec Xvid does not play in hardware decode mode but if you long press on any file you can chose software decoding mode from the meniu and it plays very smooth
3. video in mp4 format (container) with resolution 480x270, codec avc1 (H264/MPEG4 AVC) play very smooth in hardware decoding mode with both moboplayer and system player.
You can find details about video files using a free software (Gspot). Just google for it. Btw is for PC this software.
Cheers

Hello,
So facts:
MPEG4 files are correctly handled by system video player.
I tried moboplayer with 340MB video file in avi container, xvid codec, 720x576.
System player will not start this file, and moboplayer playes it but in slowmotion (video and audio continuously more and more out of sync).
I did not know of this long press mode for software decoding and will try it later.
Thanks.

If still out of sync maybe is the limitations of our wildfire s cpu. I'll try to find some video close to your specs and try. I'll let you know

My personal favourite is Rockplayer, it plays all the files I've tried. Have you tried using a video recoder on your pc to scale down the frame rates and resolution?
This greatly reduces
a) the lag
b) the space require to store them
c) the drain on the battery whilst playing them

Yes, I'm using a video converter on PC (my favorite is splash pro ex) to reduce resolution and bit rate (not frame rate); our cpu can't handle resolution too high (720x*) and high data stream. But let's be serious... the display is too small to watch a movie; maybe the only situation when I consider watching a movie is traveling by train or plane. On the other hand, is gut to know we can play videos

[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.

Tried in 3 available mode in MX Player but still laggy video

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] Is it possible to use H/W decoding to watch *.mkv in nexus 7(2013)

Have any one tried it.
Or will it be done by flashing a custom rom(may be cm10)

Yes. My sat-box records in .mkv and it is viewable (streamed from sat-box) without changing anything. I use vplayer.

I use diceplayer, works great.

+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.

MX player > settings > decoder > download custom codec

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.
u can refer to this thread ->

Unable to play 4K Videos on my Mobile!!!!

LG G4
Tried playing 4K video on my G4 and it could not handle it... only sound kept coming... *.mkv format is what I tried.
INstalled MX Player with Customer DTS codec support.. tried all..nothing helped!!!!
Please provide some help and I downloaded videos from Youtube 4K Resolution ones...

So it sounds like you downloaded a video but you don't have the codecs.
Is this happening with all videos?
I would imagine that you are able to play them just fine on youtube?

I hate to break it to you, but you won't get quicker/better responses based on how much larger you make your text.

Yes 4k does not play and but 2k(1440p) plays fine in ma youtube... But once downloaded cannot play 1440p videos using any player.. tested mx, dice, bs and stock player too

I have found the issue in playing the 4k and 2K videos I downloaded from Youtube.
I downloaded MKV format which was the culprit... 2k and 4k mp4 formats work fine... mkv works only till 1080p.. may be a codec for mkv should be released for ARM V8

test video here: http://demo-uhd3d.com/fiche.php?cat=uhd&id=149'
every video with 60+MB/s bandwith (ofc depends on storage speed, on my Samsung 32GB EVO+ even 70MB/s plays without problems) is laggy 10 bit HEVC is not playing H264 works without problems
YT 4K videos works also on VLC...

same problem

Only 4k video with h264 of codec
Maybe it's too late to reply but the fact that LG G4 only supports 4K video in h264 (mp4) format. You should convert the video with your PC (i recommends Handbrake) select 2160p profile and do some edits or you can convert with any software. Make sure the files converted to mp4. The only one reason if you downloaded a 4k youtube video and it can't directly played on G4 is just because youtube codec for 4k isn't h264 as like 1080p or lower but webm.

4K video format

Hi, anyone know if Z5P record in hevc with the 4K recording app? And if the stock video player support hevc 4k video play back? I am trying to convert some video to play my on Z5P.
