[android-developers] Re: How is RockPlayer doing hardware decoding?
hi arun, i am also facing the same problem. Only thing i understand is that it can be done using libstagefright and openmax but no dcumentation is available. If you get the solution pls do post here.

[android-developers] Re: How is RockPlayer doing hardware decoding?
Hi, ffmpeg http://ffmpeg.org/ has posted that it is possible to do H/W Accelerated H.264 Decoding on Android. We downloaded the latest ffmpeg version. There is a way to compile the stagefright library with ffmpeg. We compiled it and tried to write the wrapper class for it. The decoder got initialized but we are facing with this command: int res = avcodec_decode_video2(codecCtx, srcFrame, &frameFinished, &packet); I just would like to check if somebody has tried this approach for hardware decoding and has had success doing so.

[android-developers] Re: How is RockPlayer doing hardware decoding?
Or, crack open their app and check the build of the ffmpeg library. If they "forgot" to do the mandatory sanity checks on their build (i.e. "forgot" to read http://ffmpeg.org/legal.html that has useful build instructions) you could always request a copy of the now GPL- licensed source code to their entire application or file a takedown of their app. On Sep 10, 10:37 am, gjs wrote: > Hi, > > You should ask 'RockPlayer' > > Regards > > On Sep 9, 6:30 pm, "B.Arunkumar" wrote: > > > Hi, > > > Would somebody have some idea what exactly has RockPlayer done in > > the Hardware Decoding mode on a high level basis?

[android-developers] Re: How is RockPlayer doing hardware decoding?
They probably use FFmpeg to take care of getting the encoded media data than pushing that untouched data using some type of proxy server to the MediaPlayer to do the hardware decoding.

If authentication over rtsp is a documented standard, then you could file a bug with details and hope that it gets resolved in a future version.

[android-developers] Re: How is RockPlayer doing hardware decoding?
Hi, Regarding your question, MediaPlayer supports RTSP streaming but does not take all RTSP URLs, (with authentication, for instance). Atleast that is the experience we have had. The built in C++ RTSP Stack that comes with mediaplayer seems to have limited capabilities.

Why do you say that MediaPlayer does not support rtsp? I ask this because it does support rtsp. It's documented. The audio/video format of the stream still has to be supported by the device, though.

[android-developers] Re: How is RockPlayer doing hardware decoding?
Hi, Would somebody have some idea what exactly has RockPlayer done in the Hardware Decoding mode on a high level basis? I mean have they used the mediaplayer as it is or they have changed something at the source code level of MediaPlayer to get more improvements than the MediaPlayer (support more RTSP Url formats) and things like that?

[android-developers] Re: How is RockPlayer doing hardware decoding?
Thank you for your reply. The RockPlayer gives you the option of choosing either the Hardware or Software Decoding mode. The Software Decoding mode I am pretty sure does what you are saying, uses the FFMPEG package to decode the frames. Does the hardware decoding mode of RockPlayer also use FFMPEG? The question I have is the inbuilt MediaPlayer and VideoView classes of Android use the inbuilt hardware decoder of the device. Is the Hardware Decoding mode of RockPlayer doing something similar? A thought process along the same lines is if it possible to use the hardware decoder of the device programmatically through some means?

I believe they're using a customized build of FFMpeg that gets accessed through the NDK. FFMpeg has the ability to do a lot of manipulation with video, audio, and images.
