Cut .mkv Video using ffmpeg without changing original bitrate
23 janvier 2021, par benito_hI accidently said an unappropriate swear word during an educational video (good start I know). So I would like to remove this section from the .mkv video. However I would like the video and audio bitrate and quality unchanged.


First, I tried cutting the video slightly after the relevant time stamp without reencoding it, using for example


ffmpeg -i input.mkv -ss 00:01:09.200 -c copy -t 4:11 output.mkv



but this way the first couple of seconds seem to get lost.


Is there a way to remove the relevant segment (01:08.800 to 01:09.200) while maintaining the same bitrate / quality for audio and video ? Since only formulas are shown, a slight out-of-sync wouldnt even matter.

subprocess.Popen crashes when run in background
17 mars 2016, par user2810298In a program I’m working with right now, I try to check for the version of FFMPEG that is installed on the users machine. This works perfectly fine by using subprocess.Popen when run in the foreground OR when run in a detached screen.
However, when you run it in the background without screen (e.g. COMMAND &> /dev/null &) this process crashes the program. (see below) I’ve seen some people having similar issues on the web, but I still can’t seem to fix this...
I’ve Any ideas ?
version_ffmpeg = subprocess.Popen(["ffmpeg","-version"],stdout=subprocess.PIPE,stderr=None)
f_out = version_ffmpeg.communicate()
(then...)
if f_out --> 3rd word contains --> etc. -
