I see no problems with playback or seeking on MacBook Pro running 0.30 (MPEG2 ffmpeg decoder, OpenGL renderer), and Nviia Shield TV running 0.31-Pre (Mediacodec decoder, OpenGL renderer) and Leanback 0.203. (I can't test on VDA because my MythFrontend doesn't use it, for some reason.)<br><br></blockquote><div>The clip plays back here OK, with software decoding as mentioned but also on an Nvidia GT1030 with VDPAU decoding and also on Intel with VAAPI decoding.</div><div>Because the clip plays OK on Nvidia with hardware decoding this eliminates the possibility of a Nvidia hardware decoding bug being an issue here.</div><div>However, on Intel with VAAPI decoding and double rate High Quality deinterlacing there are many messages about interop de-interlacers being created and destroyed every few seconds.

This can be configured in Setup / Video / Playback / Current Video Playback Profile / formats > VAAPI / Deinterlacer quality (double rate).</div><div><br></div><div><br></div><div><br></div><div><br></div><div> </div></div></div>
