I've also attached a log file of the playback.

arizonamythtv: Please try the attached patch and report back if it helps or not.

comment:2 by arizonamythtv@…, 17 years ago

I'm currently using packages. I'll have to get the necessary dependencies and compile. I'll do it this weekend.

comment:3 by arizonamythtv@…, 17 years ago

I was able to compile and I can confirm that the patch fixes the issue.

arizonamythtv: awesome! thanks for testing. Janneg just informed me that the ffmpeg devs recently checked in a change to properly address the problem. Could you remove the previous patch and apply the new one I just posted and let us know if it also works? Thanks.

Resolution: → fixed
Status: new → closed

(In [22043]) increase number of probe packets and probe buffer size to fix detection of ivtv recordings

backport of ffmpeg changeset 20017. Refs #4862, Closes #7140

I removed the first patch and applied the second. Unfortunately, the problem is still occurring with the second patch.

comment:7 by tralph11@…, 17 years ago

arizonamythtv: Did you perform a make clean before you rebuilt? If not, would you mind doing a make clean; make install to just be 100% certain the most recent patch is compiled in? If it still fails could you provide a small 10MB sample. Just run the following command against the recording:

dd if=/path/to/file.mpg of=sample.mpg bs=1024 count=10000

and upload to ​http://filebin.ca/

Thanks!

Okay, I must've forgot to do a make clean. I just recompiled with the patch after make clean and I tested 10 recordings and none of them failed. Thanks for the quick fix and sorry for the added static at the end.

a patch shouldn't be necessary after [22043]
