Save the stream to mp4 files
5 mai 2012, par Ruslan SharipovHow can I keep the flow (protocol rtsp, codec h264) in file (container mp4) ? That is, on input an endless stream (with CCTV camera), and the output files in mp4 format size of 5-10 minutes of recording time.
OS : debian, ubuntu
Software : vlc, ffmpeg (avconv)Currently this scheme is used :
cvlc rtsp://admin:admin@10.1.1.1:554/ch1-s1 --sout=file/ts:stream.ts
ffmpeg -i stream.ts -vcodec copy -f mp4 stream.mp4But it can not record video continuously (between restarts vlc is a loss of about 10 seconds of live video)
