[FFmpeg-devel] Patches related to bug 4988

[Oliver Collyer]

Hi

In relation to this bug report from 10 months ago:

https://trac.ffmpeg.org/ticket/4988 <https://trac.ffmpeg.org/ticket/4988>

I’ve been having similar problems capturing video using v4l2 and the Magewell XI100DUSB-HDMI capture device.

I’ve attached some logs to the bug report to illustrate the issue plus two potential patches to address it.

I would appreciate some feedback. This is the first time I’ve looked at this area of code, so my knowledge is basic despite staring at v4l2.c and ffmpeg.c all day :)

Ideally I’d find a way for v4l2 to self-correct without the need for the “-timestamps discard” option but I’ve not yet been able to come up with anything.

Regards

Oliver
