It allows companies that build platforms e. Login or Register to post a comment. Stagefright updates can occur through the Android monthly security update process and as part of an Android OS release.

You can either get the decoded image data as raw YUV, or get it in a GL surface that you can modify using shaders. Hi mstorsjo, thanks you for quick pros and cons analysis. Thus, keep your timing in line relatively easy and it will work. Components can be sources, sinks, codecs, filters, splitters, mixers, or any other data operator.
This page was last edited on 5 Augustat I fully agree that there’s an exterme lack of documentation and support for a lot of media playback, especially in the OpenMAX world. 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. As usual nothing relevant at Qualcomm site.

It allows companies that develop applications to easily migrate their applications to different platforms customers that support the OpenMAX AL application programming interface API. Stagefright comes with a default list of lpenmax software codecs and you can implement your own hardware codec by using the OpenMax integration layer standard.
MediaCodec vs OpenMAX as implementation interface – Qualcomm Developer Network
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.
Support streaming audio and video playing for common containers. Up 0 Down 0. I have written basic player using ffmpeg but I have not been able to use hardware decoders, so not following it.
Ok, I successfully added the .so lib in the config.make :
Architecture Media applications interact with the Android native multimedia framework according to the following architecture. Syncing worked out fine till I can get decode and play done within budget.
Hi Ketan, Here are the answers to your questions. I would be doing some processing open,ax each video frames. I am open to any other framework free or commercial that would accomplish above.

This is androi last place to get any information. Skip to main content. It does not give you direct access to the decoded data either, but it is played back directly. Hi Winston, Thanks for the reply. Views Read Edit View history. This site may also provide links or references to non-Qualcomm sites and resources. This plugin links Stagefright with your custom codec components, which must be implemented according to the Openmas IL component standard.
Openmmax is not one officially supported way of playing media within the NDK, there’s actually several. It does not support other container formats. Nevertheless, this does not preclude its applicability to other sophisticated media playback and recording devices.
Stagefright audio and video playback features include integration with OpenMAX codecs, session management, time-synchronized rendering, transport control, and DRM. I am hoping that you can support streaming decoding of video mp4 etc. To set a hardware path to encode and decode media, you must implement a hardware-based codec as an OpenMax IL Integration Layer component.
Avoid writing own time sync for audio and video. The building blocks might be used to accelerate traditional computational hotspots within standardized media codecs and other integrated media processing engines. Is androd assumption correct?
