60-70 "grey" frames #9

Open rdorsch opened 6 years ago

rdorsch commented 6 years ago

Hello, I like avcut a lot, it is a nice tool running even on my ARM based systems here :-)

From time to time, but rarely I see glitches, e.g. I have an OTR video here which generates at one cut 60-70 frames which are just grey. Is that a know issue?

If not and it helps, I am happy to provide the OTR recording....

Thanks Rainer

Hi,

thank you and sorry for the late answer!

There are rare cases for which I did not find a solution yet. A small sample of the recording would be helpful, yes. Just a few seconds of the video that cause this problem. Maybe it is something I can fix.

Best regards, Mario

Hi Mario,

thanks for your reply.

I try get a smaller example, but that is not easy :-/

avcut -i test.avi -o test.mkv 0 329.68 1544.28 1877.24 3034.64 3396.08 4665.44 5092.4 6347.16 -

produces the problem at the second cut (1544.28 .. 1877.24).

When I try to make this one shorter using

../git/avcut/avcut -i test.avi -o short.avi 0 1520 1900 -

and then run

avcut -i short.avi -o short-out.avi 24.28 357.24

the cut looks fine.

Interesting enough, when I run

avcut -i test.avi -o test-out.avi 0 329.68 1544.28 1877.24 3034.64 3396.08 4665.44 5092.4 6347.16 -

that also works fine.

It seems that it is somehow relatedto the mkv output format (?).

I will try to write .avi in future and check if I eventually hit this issue as well.

Thanks Rainer

Hello Rainer,

sorry for the late response, I do not have much time to invest in avcut anymore.

I just released a new version with some fixes, could you test it again?

If it does not work, an example video would help analyzing the issue. If that is not (legally) possible, please build avcut with "make debug" and send the output.

Thank you too, Mario
