Save the stream to mp4 files

  • 772

How 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:[email protected]:554/ch1-s1 --sout=file/ts:stream.ts
ffmpeg -i stream.ts -vcodec copy -f mp4 stream.mp4

But it can not record video continuously (between restarts vlc is a loss of about 10 seconds of live video)

debian streaming video ffmpeg rtsp

    VLC does not support segmenting the output file. You can try to use directly ffmpeg as it supports output segmentation:

    ffmpeg -i rtsp://admin:[email protected]:554/ch1-s1 -c copy -map 0 -f segment -segment_time 600 -segment_format mp4 "out%03d.mp4"

  2. it may be helpful to know how to split audio files into 10 minute segments (i.e. many short files from a huge long file, e.g. for car stereo) since avconv man page has not enough explanatory value. Below is a working shell command line to split up the file "interview.mp3". using less parameters (map) did not work here. some audio files require -map 0:0 , watch output hints.

    avconv -i interview.mp3 -codec copy -map 0 -f segment -segment_format mp3 -segment_time 600 "iview%03d.mp3"
