Hello

I am developing a video player on the Raspberry Pi2 using libVLC. How do I tell libVLC to use the Raspberry Pi2 hardware acceleration (codec omxil)?

I have compiled vlc from the revision of the tag 2.1.0-git. I can use vlc with hardware acceleration:

Code: Select all

$ vlc --verbose=3 --vout omxil_vout --codec omxil video.mp4

When I start my program, I initialise libVLC as follows:

Code: Select all

char const *vlc_argv[] =
{
   "--vout",
   "omxil_vout", 
   "--codec",
   "omxil",
   "--verbose=3",
};
int vlc_argc = sizeof(vlc_argv) / sizeof(*vlc_argv);

libvlc_instance_t* instance = libvlc_new(vlc_argc, vlc_argv);
libvlc_media_t* media = libvlc_media_new_path(instance, "video.mp4");

libvlc_media_player_t* mediaPlayer = libvlc_media_player_new_from_media(media);
libvlc_media_release(media);
libvlc_media_player_play(mediaPlayer);

However, the omxil codec does not seem to be called: playing the video is as slow as when vlc_argv[] is empty and there is no reference to omxil in the verbose output while there is when I play the video from vlc.
How can I use the omxil codec from libVLC?

Thank you.

Use VLC 3.0.0 and the MMAL module.

Hi

Sorry for my late reply.

I tried to compile vlc 3.0.0 on the raspberry pi2, but I get an error, with gcc-4.8 (previous versions of gcc, 4.7 or 4.8, also fail to compile it):
/usr/include/c++/4.8/bits/move.h: In function ‘constexpr _Tp&& std::forward(typename std::remove_reference<_From>::type&&)’:
../include/vlc_fixups.h:265:54: error: types may not be defined in ‘sizeof’ expressions
# define _Static_assert(x, s) ((void) sizeof (struct { unsigned:-!(x); }))

My raspberry runs a raspbian wheezy.

Is there a special version of gcc or special git of vlc needed?

VLC compiles with gcc 4.8 on Android, so it works with this gcc.
