  • 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.

  • Can't find preset files

    1er juin 2012, par Bilthon

    this is a ffmpeg issue. I've got this error saying it could not find the hq preset file, then I read in the documentation that it looks for the preset files at 'PREFIX/share/ffmpeg' and also at '$HOME/.ffmpeg'. The thing is I'm calling ffmpeg from whithin a php file that calls a python script that finally executes the command something like 'commands.getstatusoutput(command)' so I was not sure who the user was.

    The solution ? I just used -fpre and my call now looks like this :

    /usr/local/bin/ffmpeg -i ../files/tmpvideos/myStream.flv -y -acodec libfaac -ab 96k -b 800k -maxrate 800k -minrate 600k -bufsize 800k -s 720x640 -vcodec libx264 -g 300 -r 20 -fpre /home/admin/.ffmpeg/libx264-hq.ffpreset -threads 0 ../files/tmpvideos/4647-60.mp4

    I created that directory under /home/admin and am 100% sure that there the file is there now, but still ffmpeg says :

    File for preset '/home/admin/.ffmpeg/libx264-hq.ffpreset' not found

    So I'm not sure why is it not working since I'm specifying the complete path now. Any ideas ?

    One reason that I'm thinking of, is that it maybe was not compiled correctly, like with all the flags and stuff. What I mean is that while some outputs out there looked like this :

    mine looks more like this :

  libavdevice   52. 2. 0 / 52. 2. 0
    
  libswscale     0.11. 0 /  0.11. 0

    No configuration stuff. What do u think ? could be that this ffmpeg was not compiled correctly so it will never find the presets ? I didn't compile it, so can't be sure.

    Thanks and sorry for the verbosity of the question.

  • ffmpeg & png watermark issue
