Basically after listing the hw accelerated codecs you can try to lookup the appropriate decoder with avcodec_find_decoder_by_name (since the AVHWAccel Post by Abel Alonso Hi! I'm developing a video player for Android devices using FFmpeg. Since 2011 all Intel GPUs (integrated and discrete Intel Graphics products) include Intel Quick Sync Video (QSV) — the dedicated hardware core You may see the original documentation on Libav's website here on build instructions, using the alternate hevc_vaapi on supported hardware, encoder limitations, caveats, etc. 8. libav. 265 formats are supported. 1 Description The libavcodec library provides a generic encoding/decoding framework and contains multiple decoders and encoders for audio, video and subtitle streams, and several bitstream filters. 5.
