libavcodec/qsvdec.c : missed MFXVideoDECODE_Close() call
20 juillet 2015, par Ivan Uskov -
What is an easy way to call a FFmpeg executable compiled for Android from java code ?
6 février 2013, par dentexI have compiled FFmpeg for Android to suite my needs in terms of codecs, muxers etc.
Now I have an executable that, from what I understand, should be placed in my project dir under/external//data/data//app_opt
. What I have insideapp_opt
now is :.

ffmpeg
underbin
to place in my project's/res/raw
dir ?And what is the easiest way to call
ffmpeg
and feed it with a command string ?I compiled FFmpeg with limited decoders and demuxers, because I need audio extraction only.
See : How can I get FFmpeg to locate installed libraries when —sysroot is pointing to another directory ?
I would use it in background and notify the user in notification bar on completion.
I know that, here on SO, other similar questions are present, but they are a bit vague or confusing, at least for me. I understand at this point I lack of competences (actually my App is a jigsaw made of java-code-snippets from the Net that work together).
I'd appreciate some guidance.
Thanks. -
