Hi,

I'm glad to see you :)
Well, I was quite busy at work this week.
what about your VDR system ? Have you the same errors ?
Well, my P4 2.8 GHz HT system is not powerful enough to play this stream in real time. Hence, I regularly see VDR issue CLEARs after which such messages are normal.
btw , I have uploaded one sample from AstraHD with the size 10 MB
Astra.pes http://www.zshare.net/download/1179707004348a83/
you can try it
As written above, I had to slow down replaying:
xine -S slow2 astra.pes#demux:mpeg_pes
This only gives me messages for two B pictures, i. e. you're cut VDR recording shows a picture structure like that:
IBBP....
In MPEG2, one (VDR) would have set the broken link flag for such a group of pictures as the B pictures cannot be decoded without a reference picture from the previous GOP.
But H.264 doesn't have a broken link flag, so that's why FFmpeg gives messages like the following:
[h264 @ 0xac236490]B picture before any references, skipping [h264 @ 0xac236490]decode_slice_header error [h264 @ 0xac236490]B picture before any references, skipping [h264 @ 0xac236490]decode_slice_header error [h264 @ 0xac236490]B picture before any references, skipping [h264 @ 0xac236490]decode_slice_header error [h264 @ 0xac236490]B picture before any references, skipping [h264 @ 0xac236490]decode_slice_header error [h264 @ 0xac236490]B picture before any references, skipping [h264 @ 0xac236490]decode_slice_header error [h264 @ 0xac236490]B picture before any references, skipping [h264 @ 0xac236490]decode_slice_header error [h264 @ 0xac236490]no frame!
