Hi
When we delete index file on some HD recording due to synchronous problem for editing, sometimes vdr is not able to rebuild it , start for few seconds and generate an errors
Stream has "something" in it, you can add mark but not navigate between without crashing vdr , when playing records, time goes not seconds to seconds but every two seconds
Is it possible for next release to increase the buffer size to 300 instead of 100 in recording.c , class cIndexFileGenerator ? This has been tested successfully by at least two users with same problem
Thanks in advance

If the index is initially wrong, and ok after regenerating it, this patch may fix the initial index creation:

I don't see how increasing this buffer size would change anything. cFrameDetector::Analyze() needs to see MIN_TS_PACKETS_FOR_FRAME_DETECTOR packets, which is a mere 376 byte. So even a much smaller buffer should work.
But maybe I'm missing something here and somebody can point out why increasing this buffer size would actually change anything.

It is not ok until the buffer size is increased ...
Not sure but what happen if the size of data stream between two keyframes is greater than max buffer value ? You will never be able to have inside one buffer range two I frames at the same time ? HD stream in France are not full standard, maybe to prevent copy or other
Will test your patch this week and see if it change or not index problem
Best regards

Only two subsequent TS packets are used to analyze the where a new frame starts.

I would expect this patch to fix the problem. I don't see why increasing the buffer size would help.
