Android video rotate without re-coding ?
1er juillet 2016, par user1251064i have google about this issue, and found a lot of answers. I know that we have some libraries (mp4parser, ffmpeg) witch merge, re-code, cut, etc, the videos.
I just want to play a video with the default android media player, with the right rotation on the screen (portrait or landscape), but for that do i need necessarily to re-encoding the video ?
Or is some way to achieve that without that process ?Thank you

Extract raw audio frames from OGG music file with Android NDK
31 octobre 2018, par thenaohIn my Android app, I would like to be able to process audio on the fly from an OGG file by extracting audio samples, process them and redirect them to the audio output.
I know how to make the last 2 steps using Android NDK, but I don’t know how to extract audio samples to get them in an array of floats or shorts.
I tried to make this code work that, apparently, can extract raw audio samples on the fly.
The problem is : I don’t manage to add FFMpeg in my project. I tried many tutorials (like this one), but it seems pretty difficult since I work on Windows. So after a while, I found Prebuild FFMpeg for Android, that seems interesting since it’s available for armeabi-v7a, arm64-v8a, x86 and x86_64 architectures, but again, I don’t understand how to add it in my project.
I also took a look at
libogg
,libvorbis
andvorbisfile
, but I have no idea how to add them in my project.So, does anyone have a working example on how to extract audio samples from an OGG file on the fly ?
Thanks for your help.
