Does any approach increases overhead for syncing video and audio? I would be doing some processing on each video frames. Here are the answers to your questions. Use the right library for your needs. Thus, keep your timing in line relatively easy and it will work. This is unfortunately an area that hasn’t received a lot of attention from Google. There is not one officially supported way of playing media within the NDK, there’s actually several.

You can get full implementations from 3rd parties, but in general, expect that if you want to display mp4 ts files, you’re going to androie OpenMAX and MediaCodec for everything else. There was a nice presentation I saw QC give a while ago on how to recompile the Android system to give you QC libraries you can package with your application that give full support for OpenMAX but I can adnroid longer find that presentation.

Ok, I successfully added the .so lib in the config.make :

Please note that if you use OpenMAX, you’re tacetly going to have to remember that it’s not an audio renderer; you will have to take the decoded audio and play it via OpenSLES to get something working. Like I said, there really isn’t one standard here yet.

Syncing worked out fine till I can get decode and play done within budget. I saw that OpenMAX is not fully implemented and lacks support in terms of documentation, examples etc. I fully agree that there’s an exterme lack of documentation and support for a lot of media playback, especially in the OpenMAX world.

The advantages of using OpenMAX are actually pretty phenominal. Anndroid, Google isn’t providing a complete implementation; so in this case it really falls down. What’s sad is the different levels of support even amongst different NDK versions has created a situation where it’s not easy to create sample code. I will comment on my final approach for other’s benefit.

In most cases it will provide best decoder available on the platform.
