#450(documentation:new): Specify the position of -isync more precisely

#450: Specify the position of -isync more precisely -------------------------------------+------------------------------------- Reporter: burek | Owner: stefano Type: | Status: new enhancement | Component: Priority: normal | documentation Version: | Keywords: unspecified | Blocking: Blocked By: | Analyzed by developer: 0 Reproduced by developer: 0 | -------------------------------------+------------------------------------- I've figured that the -isync option does not produce the same effect when placed in front of inputs, between the inputs and after the inputs. I just think it would be a good idea to put a little explanation in the documentation about the proper usage of that option. For example, these 2 examples produce different results: ffmpeg -f alsa -ac 1 -i hw:1 -isync -f video4linux2 -r 15 -s qqvga -i /dev/video0 -vcodec libx264 -preset ultrafast -g 15 -crf 20 -acodec aac -strict experimental -ar 44100 -ab 96k -ac 1 -f mpegts udp://192.168.25.101:10001 ffmpeg -f alsa -ac 1 -i hw:1 -f video4linux2 -r 15 -s qqvga -i /dev/video0 -isync -vcodec libx264 -preset ultrafast -g 15 -crf 20 -acodec aac -strict experimental -ar 44100 -ab 96k -ac 1 -f mpegts udp://192.168.25.101:10001 (the second example has -isync moved after the 2nd input) -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/450> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker
