Resize the video
8 juin 2016, par Android devI have a requirement for video size before upload on the server and would like to resize the video to make sure it will not go the threshold.
So far I ended up with this command :
ffmpeg -y -i E:\test3.mp4 -s 640*480 -r 15 -aspect 3:4 -ab 12288 -vcodec mpeg4 -b 2097152 E:\debug_video.mp4The issues with this command :
- is it changes aspect ratio of the video
- it works too slow (30 seconds for 12 seconds 24mb video on Nexus 5)The best solution so far for the first issue is to check the video resolution first and only than run the ffmpeg.
Do you know how to do that with help of ffmpeg as two separate commands or as a single one ? Do you know how to make it faster ? Thank you in advance
UPDATE
The console output is below. Please let me know if you would like to get console output foronProgresscallbackadb -s 07f0f4ac01897da5 logcat "ffmpeg:*" "*:S"

Recording a video using MediaRecorder
21 juillet 2016, par Cédric PortmannI am currently using the TextureFromCameraActivity from Grafika to record a video in square ( 1:1 ) resolution. Therefor I the GLES20.glViewport so that the video gets moved to the top and it appears to be squared. Now I would like to record this square view using the MediaRecorder or at least record the camera with normal resolutiona and then crop it using FFmpeg. However I get the same error over and over again and I cant figure out why.
The error I get :
start called in an invalid state : 4
And yes I added all the necessary permissions.
android.permission.WRITE_EXTERNAL_STORAGE android.permission.CAMERA
android.permission.RECORD_VIDEO android.permission.RECORD_AUDIO
android.permission.STORAGE android.permission.READ_EXTERNAL_STORAGEHere the modified code :

360 degree video of my OpenGL game
23 août 2016, par woidlerI want to make a 360 degree video of my OpenGL game.
Concerning the rendering :
Is it enough to render it in OpenGL with a specific projection matrix ?
If yes, which one ?
Or can I render it into a cube map, and then encode it ?
(Which will require much more rendering power and be more complicated, which I want to avoid)And how do I encode a 360 degree video with FFMPEG ?
