#3438: Add documentation for adding a FATE test -------------------------------------+------------------------------------- Reporter: | Owner: Timothy_Gu | Status: new Type: | Component: enhancement | documentation Priority: wish | Keywords: fate Version: git- | Blocking: master | Analyzed by developer: 0 Blocked By: | Reproduced by developer: 1 | -------------------------------------+------------------------------------- Documentation for adding a FATE test is very useful for people who submit their own small filter or decoder and who wish to add regression tests for them. Libav has a rudimentary tutorial [https://wiki.libav.org/FATE here]. The place I have on mind to store this kind of info is [[FATE/AddingATest]]. -- Ticket URL: <https://trac.ffmpeg.org/ticket/3438> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

#3433(ffmpeg:new): using "shortest" results in mismatched audio and video lengths

#3433: using "shortest" results in mismatched audio and video lengths -----------------------------------+-------------------------------------- Reporter: mjmvisser | Type: defect Status: new | Priority: normal Component: ffmpeg | Version: git-master Keywords: shortest | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -----------------------------------+-------------------------------------- Summary of the bug: "-shortest" does not add trim/atrim filters, so the length of each output stream will be a multiple of sample size. In the given example, the video is exactly 1s, but the resulting output is 1.02s. If "-t 1.000" is passed instead of "-shortest", the resulting output is exactly 1s. The difference is that using "-t" adds trim/atrim filters, so the last frame->nb_samples encoded will be truncated to fit the given duration. How to reproduce: {{{ % ffmpeg -y -probesize 500000 -f image2 -r 25 -i colorbars.%04d.png -i 100Hz_44100Hz_16bit_05sec.wav -shortest -c:v png -c:a pcm_s16le -q:v 1 -2 -f mov colorbars.mov Note that input streams have durations of 5s and 1s. % ffprobe colorbars.mov Note that the output stream has a duration of 1.02s. ffmpeg version N-60960-gf3eef02 built on Feb 28 2014 10:31:20 }}} -- Ticket URL: <https://trac.ffmpeg.org/ticket/3433> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

#3720: Support decoding of Xunlei XV file -------------------------------------+------------------------------------- Reporter: ElDimentio | Type: Status: new | enhancement Component: | Priority: wish undetermined | Version: git- Keywords: xv | master Blocking: | Blocked By: Analyzed by developer: 0 | Reproduced by developer: 0 -------------------------------------+------------------------------------- Xunlei is a major Chinese corporation with a monopoly on video downloading in China; they allow to download and play all sorts of Chinese TV shows for free but they're all in XV format, which is only supported by a video player Xunlei made. The video is H.264 video. FFMPEG cannot play this. When I try "ffmpeg -i 1.xv" I get the following: http://i.imgur.com/PrRNzvs.png Here is a link to 1.xv: https://www.dropbox.com/s/0rlzjm9b1apg0j5/1.xv 1.xv is 180MB, and it's supposed to be a video of about 45 minutes.

#3457(undetermined:new): HEVC encoding (to mkv) broken since Mar 9 in ffmpeg

#3457: HEVC encoding (to mkv) broken since Mar 9 in ffmpeg -------------------------------------+------------------------------------- Reporter: | Type: defect johnthescavenger | Priority: normal Status: new | Version: Component: | unspecified undetermined | Blocked By: Keywords: | Reproduced by developer: 0 Blocking: | Analyzed by developer: 0 | -------------------------------------+------------------------------------- So, if you build ffmpeg with x265, and try to use it to encode HEVC video to an MKV file, then it dies with the following message: {{{Could not write header for output file #0 (incorrect codec parameters ?): Invalid data found when processing input}}} This is using x265 at revision 6468. Earlier versions of ffmpeg did work, but then they started dying with that message recently. I did a git- bisect; one of the commits temporarily broke the build, so I had to skip it, but I was able to narrow it down to these: {{{ The first bad commit could be any of: a823d0948683bd97dd58556b5740e434166209a8 38aee6408a6732b8ac86341dabf6683c08caa1c1 We cannot bisect more! }}} Both of these talk about HEVC, and one talks about Matroska. (There have been API changes to x265 in the past, but in this case the problem seems to be on ffmpeg's end.)
