#6307: detected tbr different past 3.1.7 (1080i H.264) -------------------------------------+------------------------------------- Reporter: korylprince | Type: defect Status: new | Priority: normal Component: | Version: undetermined | unspecified Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- The tbr of a 1080i H.264 clip is detected differently with versions 3.1.7 and early detecting '''29.97 tbr''' (which should be correct) and versions after 3.1.7 (I've tested 3.2, 3.2.4, and current 3.3-dev) detecting '''59.94 tbr'''. I don't want to say either is wrong, because I don't know what the correct answer is; The behavior is definitely different. I don't know exactly how interlaced video works, but the fps should be 29.97 for this clip. The clip in question is recorded from a Panasonic HDC-TM700. This was discovered because newer versions of blender (including 3.2+ versions of ffmpeg) detect the given clip at 59.94 fps instead of 29.97 fps, meaning the video is imported twice as long as the audio. The bug report is here: https://developer.blender.org/T51153 I am attaching logs for versions 3.1.7, 3.2, 3.2.4, and 3.3-dev (commit efa89a8), and the clip used, 1080i_29.97.mts . Command used: {{{ ffprobe -v 9 -loglevel 99 -report 1080i_29.97.mts }}} Here is the relevant output from each ffprobe command: 3.1.7: {{{ Stream #0:0[0x1011]: Video: h264 (High) (HDMV / 0x564D4448), yuv420p, 1920x1080 [SAR 1:1 DAR 16:9], 29.97 fps, 29.97 tbr, 90k tbn, 59.94 tbc }}} 3.2: {{{ Stream #0:0[0x1011]: Video: h264 (High) (HDMV / 0x564D4448), yuv420p(top first), 1920x1080 [SAR 1:1 DAR 16:9], 29.97 fps, 59.94 tbr, 90k tbn, 59.94 tbc }}} 3.2.4: {{{ Stream #0:0[0x1011]: Video: h264 (High) (HDMV / 0x564D4448), yuv420p(top first), 1920x1080 [SAR 1:1 DAR 16:9], 29.97 fps, 59.94 tbr, 90k tbn, 59.94 tbc }}} 3.3-dev: {{{ Stream #0:0[0x1011]: Video: h264 (High) (HDMV / 0x564D4448), yuv420p(top first), 1920x1080 [SAR 1:1 DAR 16:9], 29.97 fps, 59.94 tbr, 90k tbn, 59.94 tbc }}} As you can see, 3.1.7 has 29.97 tbr, and the reset are identical and 59.94 tbr. My guess is this is incorrect, and it should be detected as 29.97 tbr. I think the problem is in libavformat judging from the comments on the blender bug. -- Ticket URL: <https://trac.ffmpeg.org/ticket/6307> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

Result: The build until c885356 (from 2017-07-02) say that muxing these streams into mp4 is currently not supported and abort. From 3b3501f (2017-07-06) onwards one gets a crash. This means that probably the commits [https://github.com/FFmpeg/FFmpeg/commit/e199d90da6473abc0d010797b14f2ae2c98… e199d90da] and [https://github.com/FFmpeg/FFmpeg/commit/38d808d72e393f9a769ef1543a7eff15fad… 38d808d7] are to be blamed. PS: The sample is quite small so that it finishes pretty much instantaneously; if one uses a bigger file (the website of the Austrian channel ORF is full of such files; some are geoblocked though) one can see that the crash happens at the end of the muxing process, probably during the finalization. -- Ticket URL: <https://trac.ffmpeg.org/ticket/7079> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

#7715(undetermined:new): Cannot build with both librtmp and native rtmp and select at runtime

#7715: Cannot build with both librtmp and native rtmp and select at runtime -------------------------------------+------------------------------------- Reporter: peloverde | Type: | enhancement Status: new | Priority: wish Component: | Version: undetermined | unspecified Keywords: rtmp | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- When building ffmepg with a 3rd party codec library that duplicates a native encoder, the choice of encoder can be selected at runtime (e.g. -codec:a aac vs -codec:a libfdk-aac). This is not the case for librtmp protocol vs native RTMP protocol (They are marked by configure to conflict: http://git.videolan.org/?p=ffmpeg.git;a=blob;f=configure;h=e1412352fa450b9d… ) This makes it difficult to use a distribution provided package and reliably get the same rtmp implmentation. -- Ticket URL: <https://trac.ffmpeg.org/ticket/7715> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
