• Unmapping memory-mapped images that are created during processing

  23 avril 2013, par user2309283

  I have a pretty big issue, although I only have the symptoms, and a theory on the cause.

  I have a C++ application under Windows 7x64 that uses system calls to FFMPEG 0.7.13 to extract frames from videos. When running, the parent application maintains a nice, predicable memory footprint in memory profilers (task manager, RAMMap) of about 2MB. I can see the individual calls to FFMPEG also come and go without incident. The trouble is, after about 100 calls to FFMPEG, and 70,000+ PNGs created (no one directory has more than 1500 pngs), the Windows memory page size raises gradually from about 2.5GB to over 7.0GB, and the system is brought to its knees. The sum of the processes for all users is no where near the reported Memory Page amount.

  I thought it might be Windows Search indexing related, so I turned off the indexing for the output directories in question using SetFileAttributes() and FILE_ATTRIBUTE_NOT_CONTENT_INDEXED, and while it seems to be working as advertised, it does not seem to combat the issue at hand. My current running theory is that all of these extracted PNGs are either fully or partially memory mapped, by FFMPEG or something else. I can also see the output PNGs under the RAMMap Physical Pages tab as standby mapped files.

  Question :
   Is there enough information here to possibly diagnose the exact problem ?
   Do I have a way to combat this issue ?

  Thanks in advance...

  Bah, il me semble que :

  - selon /ecrire/ ?exec=configurer_contenu (" Qui peut proposer des sites référencés ? " / 6forum, 1comite,0minirezo => accéder au form de proposition
  - la validation et les modifications de ce qui est publié ou rejeté devrait par défaut être réservée aux 0minirezo (ça devrait être calqué sur les articles)

  Comme c’est des autorisations sur un plugin-dist j’ai mis une estimation du temps de debug ^^

• 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.

  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.
