Since December 2016 there has been a new broadcast channel in Boston for
NBC. It is using MPEG2 1080i.
When watching a recording from this channel with VDPAU decoding, every
15 seconds or so there is pixelation on 20% to 50% of the screen. I have
tried this on 4 machines all equipped with NVIDIA Geforce 210 and they
all show the problem. All other (MPEG2 and H264) channels are perfect.
If I change playback profile to Standard decoding (ffmpeg), the playback
of the same recording is perfect. On Raspberry Pi with OpenMAX (with
mpeg2 license), the same recording is perfect. If I transcode to H264,
then I can watch using VDPAU decoding and it is perfect.
If I watch the recording files with VLC, with VDPAU selected, I see the
same pixelation.
If I watch the same file again the pixelation is at the same places,
with MythTV and VLC.
This has happened continuously since that channel came on the air and
still happens.
Has anybody else seen this? Anybody have any ideas?
Peter
