• FFMPEG av_interleaved_write_frame() : Operation not permitted

  20 octobre 2014, par camslaz

  Ok I receiving a ’av_interleaved_write_frame() : Operation not permitted’ error while trying to encode an MOV file. Firstly I need to outline the conditions behind it.

  I am encoding 12 different files of different resolution sizes and format types via a PHP script that runs on cron. Basically it grabs a 250mb HD MOV file and encodes it in 4 different frame sizes as MOV, MP4 and WMV file types.

  Now the script takes over 10mins to run and encode each of the files for the 250mb input file. I am outputting the processing times and as soon as the time on the script hits 10mins FFMPEG crashes and returns "av_interleaved_write_frame() : Operation not permitted" for the current file being encoded and all other remaining files yet to be encoded.

  If the input videos is 150MB the total time the script runs for is under 10mins so it encodes all of the videos fine. Additionally if I run the FFMPEG command on the individual file that it fails on for the 250mb file it encodes the file with no issues.

  From doing to research on the error "av_interleaved_write_frame()" it seems it is related to timestamps of what I understand to be of the input file. But in saying that it doesn’t seem to be the case in my instance because I can encode the file with no problem if I do it individually.

  example ffmpeg command

  ffmpeg -i GVowbt3vsrXL.mov -s 1920x1080 -sameq -vf "unsharp" -y GVowbt3vsrXL_4.wmv

  Error output on the failed file at 10mins. Remember there is no issue with the command if I run it by itself it is only when the script hits 10mins.

  Then it errors

       )

  Has any anybody encountered this sort of problem before ? It seems to be something to do with the timestamps but only because the script is running for a period longer then 10mins. It maybe related to PHP/Apache config but I don’t know if it is FFMPEG or if it is server config I need to be looking at.

• Use build_libstagefright in ffmpeg to build file .so for android

  21 décembre 2014, par OneGuilty

  In order to use ffmpeg in android , I tried to build ffmpeg by using build_libstagefright in

  ffmpeg/tools/lib_stagefright

  but it alwalys appear a error which i coundn’t solve it.

  the message in the bottom of ffmpeg/config.log is

• DRM for rented content ? [closed]

  1er janvier 2024, par Cromulent

  I want to be able to rent audio and video files to people. It'll just be a single payment to rent some media for three days or so but I want to use DRM so that after those three days the media stops working.

  


  It would be good if the content worked on multiple devices before the three days were up.

  


  Can someone suggest some things I should look into ? I'll be serving all my media from my own website and will ffmpeg to encode files to the correct codecs.
