Re: [Opensvcdecoder-support] open svc decoder and SVC conformance

[Mickaël R. <Mic...@in...>]

Fyi, the decoder has also been integrated into gpac player (gpac.wp.mines-telecom.fr) and there is a nice presentation of the mp4 encapsulator of it here http://gpac.wp.mines-telecom.fr/mp4box/svc/.

Most of them are shown correctly, but I have some problems with some of them. For example, with the SVCHM-1 video. Apparently, the Mplayer opens the video decoder and starts the playback of all the 300 frames, but I can not see any frame of the video. It does not give me any error. I do not understand what happened.
