Hi Started to use FFmpeg/ffvp9 to decode VP9 streams in place of libvpx ; the gain in performance is very welcome.
However, the major issue is the latency added by libavcodec ; when feeding avcodec_decode_video2 with samples, it won't return decoded frames until 16 frames have been buffered (this is the same with h264 btw). That makes ffvp9 unusable for any real-time video conference (such as webrtc). libvpx will immediately output a decoded frame, with 0 latency. Is there a way to set to AVCodecContext so it outputs frame much quicker ? Thank you Jean-Yves _______________________________________________ Libav-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/libav-user
