Guten Tag, Reinhard
Im glad to see you :)
during watching of Astra HD+ from Astra 19,2E I always have this errors
Well need to clarify what "during watching" means. See below for
details.

I think its ffmpegs problem, but I dont know how can I solve it. It seems to me, nobody from ffmpeg-devel list doesnt want to fix it. Has somebody experience with this problem ?
The above messages are OK when you switch to this channel because
we jump right into the middle of the video stream. So we will see
B pictures, which cannot be decoded without its reference
pictures (I or P pictures respectively).
ok, but I see this errors everytime :(
Moreover some pictures reference Picture Parameter Sets (PPS)
which have been broadcast just before you switched to the
channel, so these pictures cannot be decoded too.
All those errors should go away from the time on,
ah, it would be fine, but really I have this errors always during the watching AstraHD
where an IDR
picture is seen in the video stream, as all data up to the next
IDR picture will not reference any data structures broadcast
before the IDR picture.
Lets now come back to the term "during watching":
As written above, those messages are OK when switching to a
channel. When they appear "during watching" the channel, I could
think of VDR having issued a CLEAR as its buffers ran full for
any reason, but your excerpt doesnt show such messages.
Last but not least, the broadcast stream could have been "buggy".
what about your VDR system ? Have you the same errors ?
btw , I have uploaded one sample from AstraHD with the size 10 MB
