flv to mp4 boxing with avconv (or ffmpeg)

boxing / demux -> mux / containerization; keep orig. codecs, w/o re-encoding

oneliner

$ ls *.flv | xargs -I% avconv -i % -c copy %.mp4
$ ls *.flv | xargs -I% ffmpeg -i % -vcodec copy -acodec copy %.mp4

xxx.flv -> xxx.flv.mp4

rename

if you want to delete .flv, like this;

$ rename 's/\.flv\.mp4/\.mp4/' *.flv.mp4

xxx.flv.mp4 -> xxx.mp4
