And after that duration will be much greater than st->duration and I think this will cause inaccurate seek. Have tried on ffplay from Zeranoe. And also have this bug in ffmpeg 2.3.3 '''How to reproduce:''' {{{ % ffplay 05._Du_hast.mp3 }}} And then seek to end and you will see that playback not stops. '''Possible fix:''' {{{ // at begining int64_t headerDataSize = mp3->header_filesize - s->data_offset; // original code... // change duration = av_rescale(st->duration, filesize, mp3->header_filesize - s->data_offset); to this: if (filesize <= headerDataSize) { duration = av_rescale(st->duration, filesize, headerDataSize); } else { duration = st->duration; } }}} -- Ticket URL: <https://trac.ffmpeg.org/ticket/3937> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

#3517: can't set Video4Linux2 framerate ----------------------------------+-------------------------------------- Reporter: nunojpg | Type: defect Status: new | Priority: normal Component: avdevice | Version: git-master Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | ----------------------------------+-------------------------------------- ffmpeg version N-61985-gd5c0036 built on Mar 31 2014 22:09:58 with gcc 4.8 (Ubuntu 4.8.2-17ubuntu2) configuration: --enable-libx264 --enable-gpl --enable-libfaac --enable- nonfree Linux sky5 3.13.0-20-generic #42-Ubuntu SMP Fri Mar 28 09:56:33 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux My webcam supports several framerates at 640x480. If I try to grab it using: ./ffmpeg -f v4l2 -video_size 640x480 -framerate 5 -i /dev/video1 out1.avi The webcam will continue with the 30fps selected (checked with v4l2-ctl -all), while ffmpeg will output the correct framerate, by droping every 5 in 6 frames. This is a bug since ffmpeg tries to confirm the v4l2 accepts the selected framerate, but then does not select it: ./ffmpeg -f v4l2 -video_size 640x480 -framerate 3 -i /dev/video1 out3.avi [video4linux2,v4l2 @ 0x32fca40] The driver changed the time per frame from 1/3 to 1/5 In this example v4l2 reports that the webcam does not support 3fps, and the closest value is 5fps. But 30fps will remain selected! Current VLC HEAD does configure v4l2 framerate correctly. Also the framerate is being set before the video_size, which introduces probably related errors. The webcam under test supports hd1080@5fps, and hd720@10fps. According to the following examples, it changes the framerate according to the video_size that was previously selected, and not the one that is currently being selected! ./ffmpeg -f v4l2 -video_size hd720 -framerate 10 -i /dev/video1 out.avi (no errors) ./ffmpeg -f v4l2 -video_size hd1080 -framerate 10 -i /dev/video1 out.avi (no errors) ./ffmpeg -f v4l2 -video_size hd1080 -framerate 10 -i /dev/video1 out.avi [video4linux2,v4l2 @ 0x1f38a40] The driver changed the time per frame from 1/10 to 1/5 ./ffmpeg -f v4l2 -video_size hd720 -framerate 10 -i /dev/video1 out.avi [video4linux2,v4l2 @ 0x1d63a40] The driver changed the time per frame from 1/10 to 1/5 ./ffmpeg -f v4l2 -video_size hd720 -framerate 10 -i /dev/video1 out.avi (no errors) -- Ticket URL: <https://trac.ffmpeg.org/ticket/3517> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

#3760: support for animated webp images -------------------------------------+------------------------------------- Reporter: triune | Type: Status: new | enhancement Component: | Priority: normal undetermined | Version: Keywords: webp | unspecified animated | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- Currently, exporting to webp will only render a single frame. Would like to have the capability to transcode videos into webp animations similar to animated gif. The 24bit RGB space in webp should make better quality animated images. -- Ticket URL: <https://trac.ffmpeg.org/ticket/3760> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
