Like I said, there really isn’t one standard here yet.
OpenMAX AL hardware video decoding for OF Android – android – openFrameworks
It provides abstractions for routines that are especially useful for processing of audio, video, and still images. For extracting individual packets of data, there’s the MediaExtractor class, which will be useful with ahdroid common file formats for static files.
Hi, I agree completely. This is unfortunately an area that hasn’t received a lot of attention from Google. I am hoping anxroid you can support streaming decoding of video mp4 etc. As of Android 4.
Such is the world we live in. It does not support any container format at all on its own, but you as a caller are supposed to take care of that. Depending on the implementation, a component could possibly represent a piece of hardware, a software codec, another processor, or a combination thereof. 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.
Implementing custom codecs Stagefright comes with built-in software codecs for common media formats, but you can also add your own custom hardware codecs as OpenMAX components.
OpenMAX AL for Android
With MediaCodec, you need to provide individual packets of data to decode. OpenMAX AL accommodates common multimedia application use cases by standardizing a set of representative objectsas well as interfaces on those objects, to control and configure them. This page was last edited on 5 Augustat OpenMAX is used mostly by hardware vendors to provide decoders but it is almost useless at higher level. In most cases it will provide best decoder available on the platform.
Requires you to handle sync manually Ajdroid low level, requires you to do a lot of work For extracting individual packets of data, there’s the MediaExtractor class, which will be useful with some common file formats for static files.

Stagefright audio and video playback features include integration with OpenMAX codecs, session management, time-synchronized rendering, transport control, and DRM.
A platform can be compliant to one or both of these profiles by providing androix features included in a profile. Hi Ketan, Here are the answers to your questions.

Opehmax plugin links Stagefright with your custom codec components, which must be implemented according to the OpenMAX IL component standard.
This flexible core architecture allows the Integration Layer to easily implement almost any media use case and mesh with existing graph-based media frameworks. 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 use OpenMAX and MediaCodec for everything else.
The interface abstracts the hardware and software architecture in the system. Thus, keep your timing in line relatively easy and it will work.
