[issue2389] ffplay cannot seek in WMV file
Martin Lambers mar...@marlam.de added the comment: I just tested again with SVN-r26207, and it now works a lot better. Seeking generally works, but sometimes ffplay seeks to a non-key-frame, resulting in visible artifacts.

[issue2484] WMS Compatibility Suggestions
Ronald S. Bultje rsbul...@gmail.com added the comment: My idea for MMS is indeed to try RTSP, then HTTP/MMS (and I do prefer a fallback to mmst, just because some old servers still use that, even though it's not used a lot). Lack of time is the main reason that we haven't done it yet. The HTTP - MMSH forward is an interesting idea and should probably be done, but I'd need to look some more into this. You could help here by writing a good check in http.c that tries to detect MMSH input, and then I'll add the magic code to make it forward to MMSH for those streams. -- priority: normal - wish FFmpeg issue tracker iss...@roundup.ffmpeg.org https://roundup.ffmpeg.org/issue2484

Dennis dfrati...@hotmail.com added the comment: Thanks, That sounds great, right on the money. Any thought to the ASX part? I am sorry I am unable to contribute to the actual programming though. I am not familiar with C or any of the functions of FFmpeg (let alone compiling). I am more of a VB/VB.net guy...Microsoft as you can tell ;) I can help with any of the server testing though. If you need a Server 2003 WMS box to test or another WMS 2008 stream, I can do that. P.S. I was not able to set the priority to Wish, it forced to Normal.

[issue2486] MPEG-TS video not recognized with large GOP
New submission from aviad rozenhek avia...@gmail.com: when reading MPEG-TS over UDP, the stream often does not begin with a keyframe. it can therefore take some time until video information such as resolution and pixel format is discovered. I noticed that some times video resolution detection fails completely and thus the video cannot be decoded. I have found a way to reproduce it every time, by using a very large GOP. # start ffmpeg encoder ffmpeg -i file -b 2k -f mpegts -keyint_min 500 -g 1000 udp://localhost:1234 # start ffplay to read the same stream ffplay -loglevel debug udp://localhost?localport=1234 FFplay version SVN-r26095, Copyright (c) 2003-2010 the FFmpeg developers built on Dec 26 2010 04:15:49 with gcc 4.4.2 configuration: --enable-gpl --enable-version3 --enable-libgsm -- enable-libvorb is --enable-libtheora --enable-libspeex --enable-libmp3lame --enable- libopenjpeg --enable-libschroedinger --enable-libopencore_amrwb --enable- libopencore_amrnb --enable-libvpx --disable-decoder=libvpx --arch=x86 --enable-runtime- cpudetect - -enable-libxvid --enable-libx264 --enable-librtmp --extra-libs='-lrtmp - lpolarss l -lws2_32 -lwinmm' --target-os=mingw32 --enable-avisynth --enable- w32threads -- cross-prefix=i686-mingw32- --cc='ccache i686-mingw32-gcc' --enable- memalign-hack --enable-shared --disable-static libavutil 50.36. 0 / 50.36. 0 libavcore 0.16. 0 / 0.16. 0 libavcodec52.100. 0 / 52.100. 0 libavformat 52.89. 0 / 52.89. 0 libavdevice 52. 2. 2 / 52. 2. 2 libavfilter1.70. 0 / 1.70. 0 libswscale 0.12. 0 / 0.12. 0 [NULL @ 0078bd80] Probed with size=2048 and score=100 [mpegts @ 0078bd80] Unable to seek back to the start [mpegts @ 0078bd80] stream=0 stream_type=2 pid=100 prog_reg_desc= [mpegts @ 0078bd80] stream=1 stream_type=3 pid=101 prog_reg_desc= [mp3 @ 0078cd20] Header missing [mpeg2video @ 0078ed30] mpeg_decode_postinit() failure Last message repeated 57 times [mpegts @ 0078bd80] max_analyze_duration reached [mpegts @ 0078bd80] Estimating duration from bitrate, this may be inaccurate Input #0, mpegts, from 'udp://localhost?localport=1234': Duration: N/A, start: 6.12, bitrate: 64 kb/s Program 1 Service01 Metadata: name: Service01 provider_name : FFmpeg Stream #0.0[0x100], 67, 1/9: Video: mpeg2video, 25 tbr, 90k tbn, 90k tbc Stream #0.1[0x101](eng), 211, 1/9: Audio: mp2, 48000 Hz, 2 channels, s16 , 64 kb/s [ffsink @ 01efa280] auto-inserting filter 'auto-inserted scaler 0' between the f ilter 'src' and the filter 'out' Impossible to convert between the formats supported by the filter 'src' and the filter 'auto-inserted scaler 0' [mp2 @ 0078cd20] Header missing 1357.46 A-V:-1294162282.047 s:0.0 aq= 329KB vq= 5747KB sq=0B f=0/0 Last message repeated 138 times notice how resolution and pixel format information is missing and the problem of building the video scaling filter. the same command line but going through a file works, because the file does start with a key frame. -- messages: 13203 priority: normal status: new substatus: new title: MPEG-TS video not recognized with large GOP topic: avcodec, avformat, ffmpeg, ffplay type: bug FFmpeg issue tracker iss...@roundup.ffmpeg.org https://roundup.ffmpeg.org/issue2486
[issue2487] libav* reporting unneeded warnings when probing MPEG-TS over UDP
New submission from aviad rozenhek avia...@gmail.com: when reading MPEG-TS over UDP, libav*/ffmpeg/ffplay reports a lot of warnings during the probing stage. the warnings stem from the fact that UDP has no seek, and from the fact that often the first frames of the stream are not keyframes. still since these problems are to be expected, it would be nice if the warnings were not generated at all. here are the warnings: for MP2 video [mpegts @ 01d2f6a0] Unable to seek back to the start [mpeg2video @ 0075f8e0] mpeg_decode_postinit() failure Last message repeated 67 times for H.264 video [mpegts @ 01e1f6a0] Unable to seek back to the start [h264 @ 01e2b810] non-existing PPS referenced [h264 @ 01e2b810] non-existing PPS 0 referenced [h264 @ 01e2b810] decode_slice_header error [h264 @ 01e2b810] no frame!
