Hi, Thanks for you answer. I already tried this, but it still don't work. I also tried qtmux. I'm currently trying to get gstreamer-vaapi working but I still can't watch a movie accelerated by GPU :( gst-launch filesrc location=/home/alex/big.mp4 ! qtdemux ! vaapidecode ! vaapisink product a lot of: decoding to PIC_FMT_NONE is not supported decode_slice_header error no frame! but still no video. Thanks for your help.
