Hi, I'm currently working on an android video player. I am decoding audio and video in a native thread and passing the decoded data back to my application. I'm rendering a bitmap in a SurfaceView to display the video and am using a streaming AudioTrack to which I write data for the audio.
When I decode and pass audio and video seperatly this works fine; I can see the video playing smoothly and the audio is crystal clear. I use a single C pthread to decode both audio and video, the SurfaceView onDraw method for the bitmap drawing and a Java thread to play the audio. Now, since the audio and video have to run in sync, I only write the required frame audio data to the AudioTrack when needed. This way, the audio always runs in sync. However, since I'm not constantly writing audio data to the buffer to keep it in sync, there is a constant cracking sound. This is probably caused because I'm not constantly writing to the buffer. Any ideas on how to solve this? I've thought of syncing the video to the audio rather than the audio to the video, but I'm not sure what kind of effect that'll give. Many thanks. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
