[MPlayer-users] H264 HDTV streams can't be watched

[Carl Eugen Hoyos]

Hi!

When I'm watching (actually reencoding) HDTV via DVB-C (Pro7HD, Sat1HD and
AnixeHD), I always get the same errors, but at changing intervals: Video is
shown correctly, then starts being corrupt (with "concealing 4080 DC" errors),
after some time it's correct again, and so on. Audio is clear all the time.

Is anybody using DVB-S2 seeing the same problems, or is my cable provider
corrupting the stream?

I tried to upload a sample, but ftp.mplayerhq.hu did not accept a 3MB file:
229 Entering Extended Passive Mode (|||56990|)
553 Could not create file

Thank you, Carl Eugen

(In this sample, fps is not correct, but the same error occurs for samples that
are correctly recognised as being 25fps.)
