SMV file is used in portable media players with SigmaTel chip. SMV files start with WAV header, so it plays as if was an wav file, without video. MultimediaWiki explain this kind of file (it even gives the meaning of each part of the header) http://wiki.multimedia.cx/index.php?title=SMV .SMV video samples: http://samples.mplayerhq.hu/smv/ I think it's not very hard to implement this kind of container. I would be very apreciated if you guys consider implementing this. -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/412> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker

I am seeing the message below while decoding. The camera sends out slightly larger height frames than 1080 (1084). And I repeatedly get these messages about every second: Last message repeated 1 times [h264_vdpau @ 0x7f210c46df30]insane cropping not completely supported, this could look slightly wrong ... [h264_vdpau @ 0x7f210c46df30]no frame! I believe this happens during SPS/PPS parsing. I captured some raw H.264 bitstream in a file and uploaded at http://www.datafilehost.com/download-f537c855.html. Its interesting that when this video stream is wrapped within RTMP packets and submitted to flash, flash player plays it fine - with no extra 4 bytes at the top and no signs of hiccups. The parser seems to cause latency issues when this happens (stuck for couple of seconds). -- Ticket URL: <http://avcodec.org/trac/ffmpeg/ticket/411> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker

#527: NellyMoser codec reports zero frame size and bitrate -------------------------------------+------------------------------------- Reporter: DrLex | Type: defect Status: new | Priority: normal Component: avcodec | Version: Keywords: nellymoser | unspecified codec | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- While trying to play live streams that use the NellyMoser ASAO codec, we noticed that every player that uses libavformat for this (e.g. ffplay, mplayer, vlc) will freeze until the stream is interrupted. It will then play all audio that was buffered in the meantime. We traced this down to enc->frame_size being set to zero in get_audio_frame_size() in libavformat/utils.c when trying to parse the stream. If we force frame_size to some value larger than 1, the stream will play. Probably related is that the bitrate for Nellymoser streams is reported as zero as well. Yet it is easy to know the bitrate for this codec once the sampling rate is known: it is twice the sampling rate. We did not further look into this because it was easier to switch our stream source to Speex, but it does not seem too hard to fix. -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/527> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker

#468(avformat:new): No audio tracks in QuickTime

#468: No audio tracks in QuickTime ----------------------------------+---------------------------------- Reporter: Alex__ | Type: defect Status: new | Priority: normal Component: avformat | Version: 0.8.2 Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | ----------------------------------+---------------------------------- Description: No audio tracks in QuickTime Version: 0.8.2 (via brew package manager) Steps that will reproduce the problem? 1. Find a video that contains more than one audio track 2. ffmpeg -i _video.mkv -timestamp now -vcodec libx264 -acodec libfaac -alang eng video.m4v -acodec libfaac -alang ger -newaudio 3. open -a QuickTime video.m4v What is the expected result? To be able to select the audio track and to hear only one track at once. What happens instead? No audio tracks selectable. All languages/tracks are mixed into one audio track. Possible workaround: Open the file with VLC. Any additional information: Same issue with the latest libav version (although the parameters are a bit different). Also iTunes has the same issue und I'm sure an iOS device will have it too. But it seems to be a known issue since a long time: https://www.lscube.org/issue2534 I applied this patch but this only enables Quicktime to select an audio track - if no track is selected (default): all tracks are played all together.

#924: libxvid video codec leaks temporary files -------------------------------------+------------------------------------- Reporter: khali | Type: Status: new | enhancement Component: avcodec | Priority: minor Keywords: temporary | Version: 0.9.1 file | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- When encoding with -vcodec libxvid in two-pass mode, the second pass creates a copy of the first-pass log as /tmp/xvidff.*. This copy is not deleted when the second-pass encoding ends. I don't know what sense it makes to create a copy of the file in the first place, but assuming there is a good reason for that, this temporary file should be deleted by ffmpeg before it quits. I happen to have /tmp mounted in memory (tmpfs) so every file left behind is actually stealing my memory until next reboot. -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/924> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker

#653: ffplay freezes every 30 seconds when playing rtsp stream with authentication -------------------------------------+------------------------------------- Reporter: imbens | Type: defect Status: new | Priority: normal Component: | Version: undetermined | unspecified Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- Using ffplay on Win32 I am trying to play an h264 rtsp stream from an Axis camera. ffplay freezes for approx. 2 seconds every 30 seconds. When looking at the stack av_get_random_seed seems the culprit. Every 30 seconds ffplay wants to send a keep-alive message. ff_rtsp_send_cmd_with_content_async calls ff_http_auth_create_response. ff_http_auth_create_response calls make_digest_auth. make_digest_auth calls av_get_random_seed. av_get_random_seed calls get_generic_seed. It looks like get_generic_seed takes approx. 1 second to complete. -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/653> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker
