I am a developer for an Android app that uses FFmpeg to merge, compress and apply effects to video files. Previously we used a compiled FFmpeg executable that was run using a shell from our Android application (with good success). Recently I discovered a patch included in the FFmpeg master branch that takes advantage of Android's MediaCodec hardware acceleration (http://ffmpeg.org/pipermail/ffmpeg-devel/2016-July/196434.html). To utilise it, I understand FFmpeg needs to be compiled using the JNI, so I roughly followed the method described in:
https://github.com/appunite/AndroidFFmpeg I modified the code to use the current git master branch. I have used the --enable-jni and --enable-mediacodec options in my configure script. I have written some code to take a command string and run the ffmpeg.c main function. I believe I now have the system working, but I am seeing much higher memory usage than with the old executable file, for the same command. In many cases, Android kills FFmpeg / the whole app because of it. I have monitored `Debug.getNativeHeapAllocatedSize()` and see the heap growing to over 1GB on my Nexus 5X. You can see my FFmpeg command and output here: http://pastebin.com/gicyqRry I have added some of my own logs monitoring the progress file and memory usage in case that is useful. Let me know if more verbose logs are useful. I am not sure if my problem comes from the FFmpeg command, build, usage or something else. Any ideas on debugging this would be gratefully received. _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
