#3615(ffmpeg:new): -y option affects audio/video skew during screen capture
by FFmpeg 20 Jan '20

#3615: -y option affects audio/video skew during screen capture ---------------------------------+------------------------------------- Reporter: grepfor | Type: defect Status: new | Priority: important Component: ffmpeg | Version: 2.2.1 Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | ---------------------------------+------------------------------------- Example: On my system, the following script works fine and consistently renders normally synchronized audio and video: {{{ ffmpeg -f alsa -ac 2 -i hw:0 \ -f x11grab -r 30 -s 1600x900 -i :0.0 \ -acodec mp3 \ -vcodec libx264 -preset ultrafast -threads 0 \ -f matroska -y ofile.mkv }}} However, removing the **-y** option -- and assuming that a file named `ofile.mkv` already exists, so that ffmpeg asks whether to overwrite it -- results in skew between audio and video. The observed skew seems to be roughly equal to the time it takes for the user to respond to the //File exists. Overwrite?// question. This suggests that the source of the problem may be that the audio timestamp is being initialized prior to the //Overwrite?// question and the video timestamp initialized after the user response. Just guessing. In any case, omitting **-y** produces gross skew effects, and is 100% reproducible on my system. Logfiles obtained using the **-report** option are attached, one for each case (with and without **-y** option). **NOTE:** This ticket was filed with priority "important" because during my own investigation of the issue, I came across a large number of reports by others also stumped by A/V skew peculiarities when attempting aud+vid screencaps using `ffmpeg`. Many were frustrated at being unable to get any of the (numerous) cargo-cult 'recipe' commandline approaches to work. A few of the recipies do explicitly specify using **-y**, but I didn't see any explanations as to why it was necessary, and it seems (at least to me) extremely counterintuitive that that option should have any such effect. In short, aud+vid screencap seems like a not-uncommon application of `ffmpeg` and fixing this sooner rather than later may help quite a few people avoid tripping over the same issue. Just my 2c, and perhaps exaggerating the need for priority. Obviously re- prioritize as you see fit. NOTES: 0. Demo system was Arch linux, synched to repos about 2 days ago. 1. Effect has been observed using **mp3** and **pcm_s16le** audio codecs. 2. Have not tried it with video codecs other than **libx264**. -- Ticket URL: <https://trac.ffmpeg.org/ticket/3615> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
