Errors in ffmpeg while trying to encode dvb-stream

[NGage^]

Hello,

I'm getting some strange errors while encoding a http-source that Im getting from my DVB-card.
I´m using the Netstream plugin in DVBviewer to stream, the signal is direct streamcopy of the source(1080i).

Command line: ffmpeg -i http://@127.0.0.1:1234 -r 25 -vf yadif=0 -s 1280x720 -c:v libx264 -preset slow -crf 22 -level 4.1 -threads 0 -c:a copy Output.ts

Some of the errors i get:

ref 8 overflow
[h264 @ 000000000fc27400] error while decoding MB 14 54
[h264 @ 000000000fc17400] Missing reference picture
[h264 @ 000000000fc17400] decode_slice_header error
out of range intra chroma pred mode at 3 66
[h264 @ 000000000fc18de0] error while decoding MB 3 66
[mpegts @ 000000000200ad40] PES packet size mismatch
[h264 @ 000000001cbb98a0] illegal short term buffer state detected
[h264 @ 00000000056f8b00] mmco: unref short failure
[h264 @ 00000000056f8b00] mb_type 49 in P slice too large at 74 26

I get these kind of errors about 2-3 times every minutes and the consequences is obvious that i loses frames in the output.
The CPU usage rarely goes up to 90 %, I would say that it oscillates between 40-80 % so i dont think that´s the problem...
The cpu im using is a Intel 3930k i7 @ 4.3Ghz.

Would be grateful if somebody could help me out with this .

Sorry for bad english...

Clearly you need to fix such recordings FIRST. Check the tools section please.
There are almost always errors in such recordings.
Which channels you record from and which sources?


The reason is the arkward variety of transmitted formats within "the dvb standards" via sat, cable and OTA.
