Merge videos and images into a new video in Android [on hold]
10 septembre 2013, par vijayI have to create an android app that is similar to PicPlayPost.
The app should be able to do the following things :
-
Load images and videos into the corresponding blocks in the frame.
-
Resize the image.
-
Add audio to the block that contains image.
-
Play two or more videos in parallel.
-
Save the whole frame as a video clip.
I thought of using FFmpeg concatenation for this but it will not play all the videos in parallel.
I have tried to use FFmpeg with android in my earlier project and ended up with lot of issues when building latest FFmpeg with android NDK.The below link explains the usage of pre-compiled FFmpeg and OpenCV for Android.
https://code.google.com/p/javacv/#Quick_Start_for_OpenCV_and_FFmpeg
but i could not find ffmpeg-1.2*.jar there.
Is there any package to process video and playback in android other than FFmpeg ?
Thanks.

MPEG-TS, Android and FFMPEG
31 janvier 2013, par STeNI am receiving the MPEG-TS (MPEG transport stream) packets with the multiplexed H.264 video and AAC audio streams. I need to be able to show the audio and video on the Android phone. My assumption is that I need :
- MPEG-TS de-multiplexer
- AAC decoder
- H.264 decoder
- Synchronize the audio and video playback
Assuming that I am right then (in Android 2.x) MPEG-TS de-multiplexer is not part of the OS and must be ported, both AAC and H.264 decoder are part of the Android OS, but I am not sure if they have interface, which allows passing the data in buffers and if they allow mutual timing synchronization. In the worst case those components must be ported here as well.
Can you give me some advices where to start ? I was thinking about the FFMPEG porting. Are there any other ways ?

STeN
