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(avcodec:new): NellyMoser codec reports zero frame size and bitrate

#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

#968: FFmpeg crashes when transcoding a wmv video on windows 7 (64 bit) machine -------------------------------------+------------------------------------- Reporter: eiljoe | Type: defect Status: new | Priority: normal Component: | Version: undetermined | unspecified Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- This ticket continues https://ffmpeg.org/trac/ffmpeg/ticket/588 which was fixed but now when i'm running fmpeg on the full sized video (not only the first 10MB sample), it crashes around frame 1989 with message: get_buffer() failed I am using the static 64-bit Build from zeranoe @ 2012-01-27 (http://ffmpeg.zeranoe.com/builds/win64/static/ffmpeg-git-01fcbdf- win64-static.7z). You can reproduce the problem by running ffmpeg directly on the video file as it's stored on our web site, i.e.: ffmpeg.exe -i http://media.webcollage.net/rwvfp/wc/cp/3493374/module/instantupdatetest/_c… /tab-da6bd996-030a-4d8d-b4a7-105c57117116/resource-3c1aaa56-90fd- 4fb5-9383-e0606761a4ca.wmv -y bad-video.wmv -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/968> 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.
