Audio not working

[mrglobal]

Used your latest. Video works fine but Audio is scratchy and high pitched. Can you provide any guidance on this ?

Thanks

Sean

[mattip]

Can you give more details? Which tutorial, using which movie, what platform?
tutorial06 and tutorial07 work fine for me...

[solarstrings]

Tutorial 07 sound is distorted on most video files downloaded from YouTube.
Those encoded with mp3 audio seems to work though.

The sound plays ok in linux, but in Windows the sound plays distorted.

[mrglobal]

Same for me for Tutorial 07 and 04.

What about tutorials 5 and 6? Do they work?

Sorry for delay in reply

04 on windows using MSVC2010 does not work for me (I just used the latest
code).

tut05 does not compile

Error 5 error C2440: '=' : cannot convert from 'int (__cdecl
*)(AVCodecContext *,AVFrame *)' to 'int (__cdecl *)(AVCodecContext
*,AVFrame *,int)' c:\users\seanyiu\ffmpeg\ffmpeg_tutorials\test5 -
copy\test5\test5.cpp 662 1 test5

Line is :
codecCtx->get_buffer2 = our_get_buffer;

get_buffer2 has 3 arguments to our_get_buffer's 2 arguments.

Be that as it may, I don't think 05 would work too (07 does not also).
Something more fundamental is happening here. Has any one gotten 04 or any
of the tutorials working on Windows ? What might be the problem ?

By the way, I use :

"#define rint ceil" as there is no rint in MSVC2010

Thanks

That looks a bit old. It could be a version compatibility issue. Could you
try a newer ffmpeg version? Alternatively, try an older version of the
tutorials.

I had been using an earlier version of FFMPEG and kept moving to latest.
Granted it's a year dated now but I suspect it is in latest also.

@edufelipe Can you provide a sample video that people can use to reproduce this behavior?

[anarsoul]

I've debugged it a bit, and it looks like only stereo audio is affected. For some reason avcoded_decode_audio4() puts garbage in 2nd half of the buffer for files with stereo audio.

Use this youtube video (download it with youtube-dl) as a sample: https://www.youtube.com/watch?v=FKJXtXvl-HQ

[anarsoul]

On 2nd thought it looks like smaller buffer is allocated somewhere in ffmpeg internals for frame->data[0]. Insert a memset(frame.data[0], 0, data_size) after memcpy() in audio_decode_frame() and you'll get a segfault.

[anarsoul]

Got it: code can't deal neither with planar audio formats nor with sample format mismatch.

@chelyaev i got the same high pitch problem. @edufelipe was your problem solved?
