#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

#4638(undetermined:new): Multithreaded FLAC encoding

It takes so long when encoding large files at maximum compression level. Could you add multithreading to FLAC encoding? Maybe, openCL would be help common users too. flaCCL, FlaCuda are multithreaded and have better compression than that one of ffmpeg. Could you include them into ffmpeg? I hope this request won't hang here 3-2 years like many others. :'( -- Ticket URL: <https://trac.ffmpeg.org/ticket/4638> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
