Endian issue with mp4a, and mkv fix

Postby Hellimod » 12 Sep 2007 16:35

MP4A is Technically an Apple AAC standard. Windows version of VLC has an audio defect issue when playing back MP4A format. And i believe it is caused by an endian issue. PowerPC versions of VLC on the mac do not exhibit mp4a issues. Windows X86 does. Please do not trivialize the information i am giving you by asking what segment of code because i do not have the time be happy i tested this and identified the problem at all. Also do not tell me because i dont post audio codec information what i have to say is useless. I know the support game and will not enterain any attempt to put the ball in my court.

I have seen VLC developers do this constantly for those who had issues with MKV format. I will inform everyone here how to fix the MKV issue. Some people have been experiencing issues with the MKV format in Videolan due to the preload directory feature. For some reason the code is detecting perfectly good mkv files as bad files and hanging vlc. You must disable this feature in vlc by going into preferences and under demuxers and matroska, untick preload directory. VLC team should also disable this feature by default until someone can correct the preload directory code. It identifies perfectly good mkv files as bad.

1) AAC is an MPEG4 standard, not an Apple standard.

2) Matroska is a container, not a codec.

3)How do you know you are dealing with 'perfectly good MKV files'?

Who cares who made the standard. Please stop trolling. The point being is AAC is used by apple and appart of Mp4a and under some encodes requires endian conversion for presenting clean audio. Contribute or go away.

2) Matroska is a container, not a codec.

Well of course its a container and you are troll. I did not refer to it as a codec if you got that impression it is within your own mind.

3)How do you know you are dealing with 'perfectly good MKV files'?
Non Sequitor. Even if the MKV files were not proper VLC should be able to handle them without locking up. It still must be fixed.

Is there any moderators who enforce the no trolling rules around here?

What is a troll?

And what do you mean by 'I know the support game'. Isn't your attitude a little off?

well when you see post after post of real issues with vlc being posted in these forums and only getting the responce to reset your preferences and its your badly encoded files seems to put me off a little. I wanted to make it clear right away i didn't want that kind of responce. A developer should right away be able to see when there is a real issue at hand and i just handed the VLC team two issues which are real on a silver platter. And they should look into it. Since i see at least 10-20 posts in these forums about them.

Not to piss in your cheerios, but its not like they're getting anything out of this. Its a free program, they work on donations. When you gallop in here on your high horse complaining about problems like they should get right on it, I dont think its going to motivate them to help ya. Maybe you should fix it and release a new version of vlc, instead of acting like vlc should be perfect.
Just my .02, mods feel free to delete if Im "trolling".

I didn't get anything from the time i spent sorting out these nagging issues.

When mplayer can decode MP4a files just fine and powerpc versions of vlc decode without a snag but windows has issues its time to start looking at endian problems. I could care less if they ignored it. I am not a developer i dont have any vested interest in the player. I use other software to decode properly. But its about time they corrected these issues. Helping me is not an issue.

And yes your trolling. I believe i am the one doing the people here a favor not the other way around.
