Decoding artifacts,..
Not sure how interesting it is at this point of the development, but with the attached source 00006.zip the filter (like software based LWLibavSource shows artifacts, no artifacts with FFMS2, LWLibavSource with hardware decoding or DGDecNV).
Not that interesting unless it still has issues when muxed to mkv. Basically mpeg/mpegts/elementary streams will have issues the way things are done. It's been documented since day one.
Good to know. Works fine when I remux the file to mkv using mkvmerge beforehand. Thanks!
Adding observation by @HolyWu, this file has different completely linear decode output with different number of threads. Will see if FFmpeg developers are interested or at least investigate it a bit more. As usual it's h264...
