Everything else With MediaCodec, you need to provide openax packets of data to decode. Stagefright comes with built-in software codecs for common media androiv, but you can also add your own custom hardware codecs as OpenMAX components.

OpenMAX is used mostly by hardware vendors to provide decoders but it is almost useless at higher level. So if you want to do streaming playback of a format other than MPEG TS, you need to handle extracting of the packets yourself or use some other library, such as libavformat, for that task. Stagefright audio and video playback features include integration with OpenMAX codecs, session management, time-synchronized rendering, transport control, and DRM.

OpenMAX AL hardware video decoding for OF Android – android – openFrameworks

I am open to any other framework free or commercial that would accomplish above. Media architecture Application Framework At the application framework level is application code that utilizes android. Retrieved from ” https: From Wikipedia, the free encyclopedia. You must provide an OpenMAX plugin in the form of a shared library named libstagefrighthw. Post as a guest Name. I am hoping that you can support streaming decoding of video mp4 etc.

Ketan 6 This plugin links Stagefright with your custom codec components, which must be implemented according to the OpenMAX IL component standard.

MediaCodec vs OpenMAX as implementation interface – Qualcomm Developer Network

OpenMAX AL is the interface between multimedia applications, such as a media player, and the platform media framework. For extracting individual packets of data, there’s the MediaExtractor class, which will be useful with some common file formats for static files.

You can either get the decoded image data as raw YUV, or get it in a GL surface that you can modify using shaders. I will double check. To do this, you must create the OMX components and an OMX plugin that hooks together your custom codecs with the Stagefright framework. 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.

To set a hardware path to encode and decode media, you must implement a hardware-based codec as an OpenMax IL Integration Layer component. Stagefright comes with a default list of supported software codecs and you can implement your own hardware codec by using the OpenMax integration layer standard.

Avoid writing own time sync for audio and video. By clicking “Post Your Answer”, you acknowledge that you have read our updated terms of serviceprivacy policy and cookie policyand that your continued use of the website is subject to these policies. Use the right library for your needs.

I don’t think it is usable for streaming e. Support streaming audio and video playing for common containers.

It provides abstractions for routines that are especially useful for processing of audio, video, and still images. Architecture Media applications interact with the Android native multimedia framework according to the following architecture.

Forums – MediaCodec vs OpenMAX as implementation interface

Hi mstorsjo, thanks you for quick pros and cons analysis. It is an application-level, C-languagemultimedia API designed for resource-constrained devices. Up 0 Down 0. Thus, keep your timing in line relatively easy and it will work.

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

It allows companies to easily integrate new hardware that supports OpenMAX DL without reoptimizing their low level software. Content and code samples on this page are subject to the andfoid described in the Content License. If you use MediaCodec, you would need to handle sync of audio and video during playback.

Is this the best way to use hardware decoders on mobile Snapdragon on Android? The content is provided for informational purposes only and is not meant to be an endorsement or representation by Qualcomm or any other party.

Its status as an open cross-platform API enables developers to port the same source across multiple devices with minimal effort.

Requires you to handle sync wndroid Quite 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. A platform can be compliant to one or both of these profiles by providing all features included in a profile. They operate on slightly different levels of abstraction, and for most cases, MediaCodec is less work. Depending on the implementation, a component could possibly represent a piece of hardware, a software codec, another processor, or a combination thereof.
