Introduction FFmpeg is a free open-source software project comprising a large set of libraries for multimedia handling. To illustrate concepts described, the open source 3D Streaming Toolkit is used. The tutorial focuses on Intel QSV based video encoding and decoding acceleration in Windows native (desktop) applications using FFmpeg/ libavcodec for video processing. Intel QSV is supported by all popular video processing applications across multiple OSes including FFmpeg.

I have seen some posts with different information, but no idea what could be wrong in my setup.Ĭurrent configuration: TVH Build: 4.1-1183~g637d1f3 (T21:39:49+0100) Media SDK:2015 r6 Linux kernel:3.14.5 ffmpeg: 2.8.Since 2011 all Intel GPUs (integrated and discrete Intel Graphics products) include Intel Quick Sync Video (QSV) - the dedicated hardware core for video encoding and decoding. 22:28:03.569 libav: Error initializing an internal MFX session 22:28:03.564 parser: transport stream TELETEXT, DTS discontinuity. 22:28:03.564 parser: The timediff for TELETEXT is big (1710982846), using current dts 22:28:03.537 libav: non-existing SPS 0 referenced in buffering period 22:28:03.537 libav: non-existing PPS 0 referenced _ 22:28:03.537 libav: non-existing SPS 0 referenced in buffering period

However, after install tvheadend with libmfx option enabled, etc, I see the transcoding option to h264_qsv, but selecting this I only got audio and tvheadend show the following in the log: I have installed the Intel Media SDK in ubuntu 14.04 following the steps from and it was done apparentely without issues.

H264_qsv
