Hi all,
I’m new to this list so forgive me if this has been answered before.
With version 2.8 of the libraries I saw the addition of Video Toolbox hardware
decoding support (on Mac OS X that is).
But I can’t find much documentation on how to use it. There are some clues in
the header files on how to set it up, but there’s no docs on how to do the
actual decoding.
I have compiled version 2.8.1 of the libraries and I can confirm that the Video
Toolbox hwaccels are there:
Enabled hwaccels:
h263_videotoolbox mpeg1_videotoolbox mpeg4_videotoolbox
h264_videotoolbox mpeg2_videotoolbox
In my player app I have setup an AVVideotoolboxContext like described in the
headers.
if (self.codecContext->codec_id == AV_CODEC_ID_H264) {
_videoToolboxContext = av_videotoolbox_alloc_context();
int result = av_videotoolbox_default_init2(self.codecContext,
self.videoToolboxContext);
if (result != 0) {
NSLog(@"Failed to init video toolbox");
_videoToolboxContext = NULL;
}
}
_codec = avcodec_find_decoder(self.codecContext->codec_id);
Everything seems to work fine and the _videoToolboxContext is properly
allocated.
But how do I go about actually decoding using it?
Anyone with any experience from this?
best regards / Jörgen Isaksson
