I am trying to make loop video on Android tablet which has ubuntu 15.04 installed in chroot. There are ffmpeg and all Linux tools are available.
The problem that I have very limited space and ffmpeg uses temp files to recode videos so consuming additional space. Actually i do not need any re-encoding only shrinking and concatenation. For example below command joins two files and sure keeping original ones
ffmpeg -f concat -i /tmp/join.txt -c copy out.mov
Next one cut fragment and remain original input.mov video
ffmpeg -ss 00 -i input.mov -t 90 -c:v copy -c:a copy out.mov
Is it really possible to accomplish such editing without keeping original files ? E.g. when editing taking place, in same time delete finished parts to preserve space.
UPD. According to below answers and my searches it is not possible. Thanks for participating.
