Hello everyone , I'm currently on a Udoo ultra with ubuntu trusty 14.04 installed on it . I saw there was a encoder and decoder for h264 format on the board . I wanted to stream the camera (a common c920 logitech for example),which has an output in h264, and decode it using gstreamer with hardware decoder. I saw that i need to install vaapi plugins for gstreamer to work that way https://stackoverflow.com/questions...erated-video-encoding-of-gstreamer-on-android but I didn't find a proper way to install it on my configuration , And didnt find any clue if it will work at all . I started by trying installing libva to work with vaapi from source. Configuration is ok, make and make install too . But when i want to run command " sudo vainfo" to check everything is correct i get : Code: error: XDG_RUNTIME_DIR not set in the environment. error: can't connect to X server! libva info: VA-API version 0.35.0 libva info: va_getDriverName() returns 0 libva info: Trying to open /usr/lib/x86_64-linux-gnu/dri/i965_drv_video.so libva info: Found init function __vaDriverInit_0_35 libva error: /usr/lib/x86_64-linux-gnu/dri/i965_drv_video.so init failed libva info: va_openDriver() returns -1 vaInitialize failed with error code -1 (unknown libva error),exit Is the proccesor currently supported by vaapi ? if not, Is vaapi the correct plugins I need to install to work with HW encoder/decoder ? Does anybody have advices/tutorials on that ? thank you for your answers !
