• ffmpeg for android build - is it complete

  3 février 2015, par Robert Rowntree

  //EDIT save time and refer to the SF project . IMO, it may save a ton of work getting up to speed.....

  after more work on this issue :

  added a git project

  build is easier with custom toolchain installed so that you can invoke compiler the easy way

  sample stdout from ndk-build

  —
  originally used ubuntu 12.04 inside vmplayer on windows vista. IMO linux is better for builds than cygwin.

  I follow these instructions getting a indeterminant outcome in which the following conditions exist.

  build_android.sh seems to exit normally
  config.log has error where confirming gcc from crosstoolchain
  all the static libs are built ok
  (./libavfilter, ./libavcodec etc )
  ffmpeg.o is there and executes ok
  no ./android directory as per the prefix setting to config

  it looks like i can just push the binaries to my phone and test in a shell. If that’s ok then i can look to a jni wrapper for the static libs.

  But why didn’t the build write anything to —prefix=./android/armv7-a ??
  that path does not exist at the conclusion of the build

• 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.

  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.
