[issue1978] Change default number of RTSP audio channels to 1
New submission from John Wimer j...@god.vtic.net: I recently ran into a problem with ffmpeg decoding a mono audio RTP stream over, and found that I wasn't the first one with this problem. I saw this email from a few years ago but it was never addressed. [http://lists.mplayerhq.hu/pipermail/ffmpeg-user/2007- November/012266.html] From reading the RFC that describes the SDP format, which is used by RTSP to describe the RTP streams, I see that if no parameters are given, the number of channels will be assumed to be one. From [http://www.ietf.org/rfc/rfc2327.txt] page 21: The general form of an rtpmap attribute is: a=rtpmap:payload type encoding name/clock rate[/encoding parameters] For audio streams, encoding parameters may specify the number of audio channels. This parameter may be omitted if the number of channels is one provided no additional parameters are needed. For video streams, no encoding parameters are currently specified. The attached patch changes the default number of channels to match the the rfc. -- messages: 10674 priority: normal status: new substatus: new title: Change default number of RTSP audio channels to 1 topic: rtsp type: patch FFmpeg issue tracker iss...@roundup.ffmpeg.org https://roundup.ffmpeg.org/issue1978

[issue1972] VOB parser does not find all available streams
Michael Niedermayer michae...@gmx.at added the comment: On Sat, May 29, 2010 at 06:00:08AM +, blindbunny wrote: New submission from blindbunny ffmpegbugs.10.noonee...@spamgourmet.com: My goal is to identify the streams in a DVD VOB file and later recode them. However, ffmpeg -i does not list all streams, so recoding them is not possible either. This is true for offset 0 of the first VOB file as well as any other offset in any other VOB file from the same set, although different streams are missing depending on the file/file position. mplayer detects and plays all streams from the same file successfully. For example, the command 'ffmpeg -v 9 -loglevel 99 -i /tmp/test.VOB' does (in contrast to mplayer) not detect the audio streams present in the program stream: FFmpeg version SVN-r23349, Copyright (c) 2000-2010 the FFmpeg developers built on May 27 2010 15:49:21 with gcc 4.4.3 configuration: --enable-nonfree --enable-gpl --enable-postproc --enable-avfilter --enable-avfilter-lavf --enable-pthreads --enable-libx264 --disable-stripping libavutil 50.16. 0 / 50.16. 0 libavcodec52.72. 0 / 52.72. 0 libavformat 52.66. 0 / 52.66. 0 libavdevice 52. 2. 0 / 52. 2. 0 libavfilter1.20. 0 / 1.20. 0 libswscale 0.10. 0 / 0.10. 0 libpostproc 51. 2. 0 / 51. 2. 0 [NULL @ 0xa46b510]Probed with size=32768 and score=52 [mpeg @ 0xa46b510]probing stream 0 Last message repeated 4 times [mpeg @ 0xa46b510]Probe with size=10112, packets=5 detected mpegvideo with score=51 [mpeg @ 0xa46b510]probed stream 0 Input #0, mpeg, from '/tmp/test.VOB': Duration: 00:00:00.48, start: 0.214389, bitrate: 1450 kb/s Stream #0.0[0x1e0], 22, 1/9: Video: mpeg2video, yuv420p, 720x576 [PAR 64:45 DAR 16:9], 1/50, 9800 kb/s, 25 fps, 25 tbr, 90k tbn, 50 tbc Stream #0.1[0x20], 1, 1/9: Subtitle: dvdsub Stream #0.2[0x21], 1, 1/9: Subtitle: dvdsub Stream #0.3[0x22], 1, 1/9: Subtitle: dvdsub Stream #0.4[0x23], 1, 1/9: Subtitle: dvdsub Stream #0.5[0x24], 1, 1/9: Subtitle: dvdsub Stream #0.6[0x25], 1, 1/9: Subtitle: dvdsub Stream #0.7[0x26], 1, 1/9: Subtitle: dvdsub Stream #0.8[0x27], 1, 1/9: Subtitle: dvdsub Stream #0.9[0x28], 1, 1/9: Subtitle: dvdsub Stream #0.10[0x29], 1, 1/9: Subtitle: dvdsub Stream #0.11[0x2a], 1, 1/9: Subtitle: dvdsub Stream #0.12[0x2b], 1, 1/9: Subtitle: dvdsub Stream #0.13[0x2c], 1, 1/9: Subtitle: dvdsub Stream #0.14[0x2d], 1, 1/9: Subtitle: dvdsub Stream #0.15[0x2e], 1, 1/9: Subtitle: dvdsub Stream #0.16[0x2f], 1, 1/9: Subtitle: dvdsub Stream #0.17[0x30], 1, 1/9: Subtitle: dvdsub Stream #0.18[0x31], 1, 1/9: Subtitle: dvdsub Stream #0.19[0x32], 1, 1/9: Subtitle: dvdsub At least one output file must be specified this looks like MAX_STREAMS is hit [..] FFmpeg issue tracker iss...@roundup.ffmpeg.org https://roundup.ffmpeg.org/issue1972
