  Hi,

I found the problem. VDR does not detect the frame independent in this
stream because in the function :

cFrameDetector:: Analyze (const uchar * Data, int Length)

in the file remux.c.

((Data [i +2]>> 3) & 0x07) is equal to 0 instead of 1 for stream that work.

I applied this patch :


and record is working again.
I do not know what has changed in the stream.

I tested this patch since yesterday and so far I have not had any problems.

What do you think?

Senufo

If this stream marks independent frames with '0' instead if '1',
I would say it is broken.
