Hi, I have a problem with sound playback in 3gp files using the latest cvs code. mplayer produces the following message, and there is no sound. Opening audio decoder: [ffmpeg] FFmpeg/libavcodec audio decoders dec_audio: Allocating 192000 + 65536 = 257536 bytes for output buffer. FFmpeg's libavcodec audio codec INFO: libavcodec init OK! ds_fill_buffer(d_audio) called seek to 0x82CC s->pos=9E28 newpos=8000 new_bufpos=82CC buflen=0 WARNING!

Starting playback... [amr_nb @ 0x8693da8]amr frame too short (4, should be 16) Using gdb, I found that only 86 bytes of audio data was being sent to the decoder, instead of 5504 bytes. There is some code in demux_mov.c that is commented out that corrects for the samplesize not being 1. Putting back the commented out code results in correct audio playback. Following is a diff for the code in question. --- MPlayer-cvs-20060405/libmpdemux/demux_mov.c.orig 2006-03-27 22:37:18.000000000 +0100 +++ MPlayer-cvs-20060405/libmpdemux/demux_mov.c 2006-04-07 13:33:53.000000000 +0100 @@ -1911,9 +1911,9 @@ { mp_msg(MSGT_DEMUX, MSGL_DBG2, "WARNING!
