[MPlayer-users] Was mplayer better in 2006 ???

[Emmanuel Anne]

Yeah I know, but if I send the whole output of -v while playing a stream, I
will spam it, really, because it's very long !
Anyway if I skip the detection part and get to the main part, you get

version from 2006 :
Opening video decoder: [ffmpeg] FFmpeg's libavcodec codec family
INFO: libavcodec init OK!
Selected video codec: [ffh264] vfm: ffmpeg (FFmpeg H.264)
...
==========================================================================
Opening audio decoder: [faad] AAC (MPEG2/4 Advanced Audio Coding)
dec_audio: Allocating 4608 bytes for input buffer.
dec_audio: Allocating 49152 + 65536 = 114688 bytes for output buffer.
...
FAAD: Decoder init done (4608Bytes)!
FAAD: Negotiated samplerate: 48000Hz  channels: 2
FAAD: compressed input bitrate missing, assuming 128kbit/s!
AUDIO: 48000 Hz, 2 ch, s16le, 128.0 kbit/8.33% (ratio: 16000->192000)
Selected audio codec: [faad] afm: faad (FAAD AAC (MPEG-2/MPEG-4 Audio)
decoder)

And the 2011 version :
Opening video decoder: [ffmpeg] FFmpeg's libavcodec codec family
[h264 @ 0xdcd260]Unsupported bit depth: 0
INFO: libavcodec init OK!
Selected video codec: [ffh264] vfm: ffmpeg (FFmpeg H.264)
==========================================================================
==========================================================================
Opening audio decoder: [ffmpeg] FFmpeg/libavcodec audio decoders
dec_audio: Allocating 192000 + 65536 = 257536 bytes for output buffer.
FFmpeg's libavcodec audio codec
[aac @ 0xdcd260]Unsupported bit depth: 0
INFO: libavcodec "aac" init OK!
lavc_audio: error

After that you get tons of output like :
AAC SYNC AFTER 390 bytes

AAC_PROBE: 6144 bytes
AUDIO PAYLOAD: f9 58 80 30
AUDIO PAYLOAD: 58 80 30 ff
AUDIO PAYLOAD: 80 30 ff fc
...
but it can never decode the audio correctly anyway.
You get the same thing for hd and low bitrate h264 streams.

I finally found a problem with the 2006 version, it can't seem to decode
some hd channels from the dvb card, like the 2011 version it thinks it's an
mpeg2 stream and gets stuck, and -demuxer lavf doesn't help it.
The 2011 version is helped by -demuxer lavf (you get a picture), but no
sound.

If you want the whole output, I'll attach a file !
