HTC Desire eaac+ decoding - problem with android decoder?

Hi,
I have all my music library encoded as eaac+ 48kbps parametric stereo as this allows me to fit my entire music library on my microsd card.
Been using my music collection on my HTC HD2 which i soon replaced with the Desire.
Thing is that after some of the tracks i've been listening to started sounding funny, i've investigated more on the issue to find out that the Android eaac+ encoder seems to be doing quite a bad job...
For example the .aac file i've attached sounds almost perfect on my laptop and HD2 (using the same hi quality Sennheiser headphones) but on the desire the low bass sounds are awful, it's just like someone is hitting on a broken drum.
Could someone please help me confirm this issue? Could you try playing the attached test .aac file on the htc desire and let me know if you encounter the same problem with it sounding awful? (Try also on a laptop with latest winamp to see the difference).
Thanks !

Hi ubik,
All my digital audio files are also eaac+ at 48kbps, but are in .m4a containers, not .aac, but that shouldn't make any difference (By the way aac+ with parametric stereo = eaac+). As I'm about to buy a Desire, your post made me think that maybe the Desire doesn't support eaac+, only aac+. Iphones and ipods only support aac+, so eaac+ files come out in mono and sound rubbish on those devices. HTC's website doesn't confirm if the Desire plays eaac+ files, so I contacted HTC via their website, and they confirmed that the Desire supports these audio formats .wma, .aac, .m4a, .mp3, .mp4 and .wav files And these codecs WAV, WMA, AAC, AAC+, eAAC+, M4A, MP3 and MP4. Therefore if it supports the eaac+ codec, you should get CD quality sound with your eaac+ files at 48kbps. Maybe you should ask HTC about this via their website.

That's funny, I contacted HTC support about playing .m4a files and the reply was, and I quote, "You can not play the m4a files by default on your device and you need to search over the Android market for a compatible application with your device to allow you play such files on your device."
I myself haven't been able to playback .m4a files with several music players, including the default HTC one and players downloaded from the market.
Is anyone actually able to play this file type?

What i did is dump my eaac+ converted music library as it sounded bad on my Desire and it was really a lot of music that i did not listen to; being a lot of media files, the music player was very sluggish. I reordered my original mp3s and made a selection of music that i do listen.
I admit, this is not the solution to the problem (using mp3s instead of eaac+ and using less files because the player is sluggish) but it is a great phone overall and who knows what the future brings (Android 2.2 Froyo for example).
I'm not impressed with how google has failed to respond my bug report, but it's hard for me to find faults with this phone, after using the HTC HD2 i'm wondering how i could live with winmo's faults all this time

Hey,
I plan to buy a Desire, but this could be a dealbreaker for me:
Does this occur with AAC+ (e.g. HE-AACv1, without Parametric Stereo) as well? My whole music library is in that format!
It would be really great if somebody could confirm the situation. If you don't have access to any AAC+ files of your own, I uploaded one to drop.io/3q2r8b7/asset/desire-heaac-test-zip in MP3, AAC+ (HE-AAC v1) and eAAC+ (HE-AAC v2).
Thanks!

hi,
all three files sound ok on my desire (i can tell very little difference between them)
maybe you should try giving me something with more base sound (this is where i notices the problem)
you gave me symphonic music which has more of the high notes

Thank you very much for testing.
I've now uploaded another track with more bass in it: drop.io/3q2r8b7/asset/backleg-heaac-test-zip

Hi,
i've tried these three files on my desire and they sound just fine !
can you tell us the exact settings u've used for music encoding? we might be onto something here...

I've encoded them with the Nero AAC Codec, Version 1.5.4.0, with the command line parameters -br 32000 for the v2 one, and -br 48000 for the v1 (Nero autoselects the appropriate codec for the chosen bitrate that way).
Did you encode your 48kbps files to HE-AAC v2? That could be the cause of your problem; v2 uses Parametric Stereo, which can improve quality for very low bitrates (<32kbps); but for 48kbps you usually get better results with just using HE-AAC v1.
Be sure to use the newest version from www .nero.com/enu/downloads-nerodigital-nero-aac-codec.php, as the change log specifically mentions some fixed incompatibilities with some hardware devices.

my files for the most part are AAC in mp4 or m4a extensions.
done myself with belight and neros AAC encoder. haven't had any problems at all with the default player or meridian
p.s some are about 2-3 years old at least and still play fine. older ones are mp3 though

I had a similar problem with my Desire. Music sounded AWFUL. Lots of clicks and pops on drum sounds. I normalized the mp3s to 90% and it seems to have fixed it.

Video playback

Hi peeps, just curious to see if anyone knows of a media player that plays. Mp2 files. I have a tv decoder which records and can export via a usb socket. But when I copy the video files over nothing seems to play them. They list as Mp2, any helps good thanx in advance.
Sent from my HTC Desire using XDA App

mp2 is an audio only format, isn't it?
Can you play the format on a desktop machine at all? What application do you use to playback?
Maybe you could try use a piece of software to analyze the file? Maybe Gspot.

Hi, back again.Tried what you suggested.I can play it on a PC using VLC and after running it through GSpot i get this info.Any ideas?
File Type: MPEG-2 Transport Stream
Mime Type: video/mp2t

Sorry, not sure what will play that back, maybe RockPlayer... However they are actively working on a VLC android port. Not sure about ETA but the last I heard (December 2010) was "very soon".
Until then, maybe try converting the file to something more common. There are plenty of free convertors out there.

@stigslim:
You try to play Mpeg2 Transport Streams ( mp2ts ).
And because MPEG2 needs extra licenses you have to buy the Cinema Plugin.
You can also try Rockplayer or Vitalplayer from the market.
And dont forget to rename the files to .ts

Mpeg2 does not need cinema plugin. Only mpeg2 when sound is encoded as 5.1 ac3 sound does it need cinema plugin. Mpeg2 with any other audio track plays fine. It is actually the ac3 5.1 coded that cinema plugin supports not specifically for mpeg2 at all.
John

The Cinema Plugin is needed for AC3 ( you are right ) and MPEG2.

It is not needed for mpeg2 at all. Every mpeg2 will play except an mpeg2 that has 5.1 ac3 sound in it.
Ac3 will also play without plugin if it is 2.0 it's only 5.1 that needs the plugin.
Try an play an MPEG 2 field that does not have an ac3 5.1 audio track and see what happens.
John

I have tried MPEG2 and MP2 files without AC3 and they are not played. A message is shown, that I would need cinema plug-in to play those file formats.

Hi, back again.I tried Rockplayer with no luck so I gave vitalplayer a go and it seemed to play it pretty good but had a bit of a problem with timing but that could have been a corrupt video file.I will try another clip and be back to let you know how I get on.

Second that. With an 101 with Firmware 1.0.84 (I'm holding out until they release the official flash support). Doesn't play mpeg2 files without plug-in!
To the thread starter: Just spring that 15 quid. Just thinks of it as a final installment to get all the features of the archos

Video player with all format compatibly

Suggest me one video player which can play all the formats of video such as .avi, .mpg etc etc.

VLC is pretty great for being an alpha. Stock player is still the best though.

Nothing beats stock player atm. I'm on CM7, so I don't have the flawless Samsung player, hence I also need a replacement. The best I've got so far is mobo player, however it can't handle HD videos that well. There's also Rock player, but to me it seemed even worse than Mobo player. I've also gave VLC player a try, but in this alpha stage it's unusable; it has lower than 1 FPS on HD videos. So, I'm waiting for improvements on either of them.

I use QQPlayer for playing RMVB files. Super I should say

Vplayer, all the way.

Multi audio track in single file.
Single MKV/MP4 file may have 2 or more audio track.
some players like dice,mx can choose audio track.

Ohk. Thanks

There seems to be 2 Mobo players on the market. The original one, and a "newer" one. No idea if the newer one is legit or notably different.
Generally, there is very little the stock player won't handle, if you find something then Mobo seems to be able to deal with it.

My Samsung Galaxy s2 Stock Media Player dosent play ac3 Audio files or Mp4 Files with Ac3 audio decoded. I was able to play those using Dice player or rockplayer. But i dont have an option called 5.1 to enable on those players unlinke stock player.
The official Samsung Site or other specification gives the specification (This is from wikipedia)
For audio it supports (FLAC, WAV, Vorbis, MP3, AAC, AAC+, eAAC+, WMA, AMR-NB, AMR-WB, MID, AC3, XMF). For video formats and codecs it supports (MPEG-4, H.264, H.263, DivX HD/XviD, VC-1) and video formats (3GP (MPEG-4), WMV (ASF) as well as AVI (DivX)).
Issues:
1. Stock Media Player dosent play ac3 Audio files or Mp4 FIles with Ac3 audio decoded (Stock Media Player gives the Option 5.1 to be enabled but ac3 not playing)
2. Other players play it Under software decoding, But main Problem is 5.1 isn't working with Head phones
I googled and found some Users were able to Play it with stock media Players. Read something like "I dont have any problem playing those files, I just copy and play them"
I am now confused is this happeneing with my device alone, So guys how do you dea this?
Please reply so that i would be grateful to you guys

Until someone makes video codec for the sg2 Mali gpu, no software codec will be able to handle high res video better than the stock video player, or lower res video with the same battery efficiency.
That being said, audio decoding and subtitle handling don't need that horsepower, and more and more players mix stock decoder hardware features for the video part and software management for the rest.

Something is wrong or missing, can't really give you an answer because I never seen that happen before. Should give more info about the file your trying to play.
Besides that, why not just stick to the 3rd party apps. I stop using stock since it barely plays anything correctly compared to both MX and Dice player anymore. Or is that 5.1 sound effect really that necessary to you?

[Q] [MKV] Hardware Accelerated Video Decoding?

Hey guys,
I was wondering if there was a way of making the Arc use Hardware decoding for MKV video.
I've tried every last tip google can give me and every single HW ACC supporting media player in the market but they ALL fail to either enable HW and default to SW or just crash all together when trying to play MKV files.
MP4 files (i.e. Youtube 1080p via WiFi) run perfectly fine with HW decoding on MX Player only if I try to watch a 720p/1080p MKV file, mostly TV shows and movies, it stutters like mad and the audio lags behind on whatever player I grab. Some players work better then others and MX player performs the best but still unwatchable.
I'm running a Xperia Arc with the CM 7.2.0 FXP052 ROM and Kernel OC'd @ 1612Mhz. On stock speed it's MUCH worse but the kernel doesn't go higher then 1.6Ghz nor do I think the phone can handle anything more then that without messing with the voltages.
So, is there any way to make it run HW ACC mode for MKV or am i and the rest of the Arc users just screwed?

Looks like I have to bump it up a bit...

Have you tried other players too?
I've never watched *.mkv files, because I always use *.avi files.
And I never had any issues with watching HD videos.
Btw, I'm using QQ player.

xperia hadware doens't support mkv but you can try another players like rockplayer and run software decoding.

You can smoothly run H/W accelerated mkv 720p videos and other formats on your smartphone using Dice Player or BS player. These players support H/W ACC for mkv,avi,flv and others.

I use Dice player to play mkv videos but not all mkv videos can be played i H/W mode and I think I know why. Developer of DicePlayer wrote in description that Xperia arc can play "720p [email protected]/4.0(some Level 4.0 file have shutter problem)" videos. From what I know scene releases of tv shows and hd movies now need to be converted with 4.1 profile so our arc/arc s can't play it. There is no need to reconvert video to change Profile Level to 4.0 or 3.1 thanks to H264 Level Editor tool. It can change level within 1 second. Tested with justified.s03e04.720p.hdtv.x264-compulsion.mkv. Changed level from 4.1 to 4.0 and still couldn't play it via DicePlayer so I changed it to 3.1 and it worked like a charm.
Don't know why but video still can't be played in MX Video Player.
I just hope this can be usefull to somebody having touble with playing 720p mkv videos.

THIS! THIS IS IT! I spent a couple hours poking around for the answer and found thread after thread of people suggesting 'hey have you tried this player yet?', but THIS IS THE ANSWER!
Thank you so much!

Hi all, I wanted to ask if anyone found a way to play 720p .mkv files (mainly TV Scene Releases) on our Xperia Arc and with what settings (ROM, Kernel, CPU Frequency, etc) and which Video Player.
I've read that you can do it with changing Profile Level of the .mkv but I am a Mac user and can't run H264 Level Editor. Can we do it perhaps with another mac-compatible application?
Thank you for your time.

HE-AAC - Poor decoding :(

Hi,
Anyone here use HE-AAC files? Is there any workaround or fix. Is anyone able to play 64kbps encoded HE-AAC music files in this phone with quality? 64kbps HE-AAC is supposed to give 192kbps Mp3 music quality.. i've been using HE-AAC on my xperia and previous smartphones.. however HE-AAC files are not at all working properly with samsung phones, its not androids fault as my xperia can play them. However my samsung wave 3 and galaxy w is unable to decode them properly, they are decoding HE-AAC as LC-AAC
