  • Recording video by the hour to file (avconv/ffmpeg)

    13 novembre 2013, par JohanS

    I'm currently recording video from my IP camera to disk by making use of avconv (ffmpeg).

    avconv -i rtsp://192.168.1.1/stream -c copy pool.mp4

    However, I'm in need of following and have not been able to successfully get it running from a bash script or cron.

    • Create a new file per hour and name it accordingly
    • I have to support multiple cameras
    • I need to limit to a weeks worth of recordings whereafter the oldest gets deleted.
    • I want to manage this via a bash script and/or cron job as far as possible.

    Thanks

  • Set timeout on ffmpeg process

    30 octobre 2013, par Thomas Vervik

    Sometims ffmpeg never completes, and thereby preventing conversions of other videos in the queue. Is it possible to set some sort of timeout in ffmpeg such that it terminates if it isnt finished within some given time, example 5 min

    My command looks like this today :

     ffmpeg -i /home/tomcat/bsafevideo/1efef9daa7f5000ed83d67f6fbd0e7d9/aad5adc307c4dd7e457509423a7f3734/69451c31cd592e86138423f6849d8141 -y -r 24 -ar 22050 -f mov -vf [in]transpose=1[rt0],[rt0]scale=iw*480/ih:480[sc0],[sc0]pad=640:480:140[pd0],movie=/srv/bsafe/tomcat7/webapps/ROOT/resources/images/logo_watermark.png [wm],[pd0][wm] overlay=W-w-140:0[out] /home/tomcat/bsafevideo/1efef9daa7f5000ed83d67f6fbd0e7d9/aad5adc307c4dd7e457509423a7f3734/69451c31cd592e86138423f6849d8141.mov -ar 22050 -b 1500k -vcodec libtheora -acodec libvorbis -f ogg -vf [in]transpose=1[rt0],[rt0]scale=iw*480/ih:480[sc0],[sc0]pad=640:480:140[pd0],movie=/srv/bsafe/tomcat7/webapps/ROOT/resources/images/logo_watermark.png [wm],[pd0][wm] overlay=W-w-140:0[out] /home/tomcat/bsafevideo/1efef9daa7f5000ed83d67f6fbd0e7d9/aad5adc307c4dd7e457509423a7f3734/69451c31cd592e86138423f6849d8141.ogg -ar 22050 -vcodec libx264 -profile baseline -vf [in]transpose=1[rt0],[rt0]scale=iw*480/ih:480[sc0],[sc0]pad=640:480:140[pd0],movie=/srv/bsafe/tomcat7/webapps/ROOT/resources/images/logo_watermark.png [wm],[pd0][wm] overlay=W-w-140:0[out] /home/tomcat/bsafevideo/1efef9daa7f5000ed83d67f6fbd0e7d9/aad5adc307c4dd7e457509423a7f3734/69451c31cd592e86138423f6849d8141_mp4.mp4

    UPDATE. Thanks LordNeckBerd, you pointed me in right direction !

    So I see now its kind of not ffmpeg really hanging, the issue is that my java code which reads the inputstream from the linux process will block since ffmpeg never returns a end of line, which I see now when Im running the command. This is the blocking line, it waits for more input from me.

    Press [q] to stop, [?] for help

    So its two issues here now. First is why this particular conversion is failing, and second, how to make sure ffmpeg is not making this (for my Java process) blocking command asking for more input.
