Hi Ti expert:

We encountered an issue while using Gstreamer H265 encoding on the Linux SDK 11.0 TDA4VH platform.
During testing, we found that the video turns gray after encoding around 130,000 frames, as shown in the screenshot below.
When checking the kernel logs, we noticed the following two lines appear at the time the problem occurs.
Have you ever encountered this issue before? Do you have any suggestions for a solution?

our Gst pipe cmd:appsrc format=GST_FORMAT_TIME is-live=true do-timestamp=true block=false name=myAppSrc0 ! queue
! video/x-raw, width=(int)1280, height=(int)384, framerate=(fraction)30/1, format=(string)NV12, interlace-mode=(string)progressive, colorimetry=(string)smpte240m
! v4l2h265enc
! video/x-h265
! h265parse config-interval=-1
! queue ! appsink name=myAppSink0 max-buffers=50 drop=true

Thanks and best regards.

Hello,

Apologies, for the delay. Is this error occurring only after 130,000 frames or is it also occurring before? I will provide an update on my results in the next 1-2 days.

Thanks,
Sarabesh S.

Hello,

We tested around 130000 frames and it will appear, but it will not recover afterwards. Of course, this number may change, not necessarily 130000 frames.

Thanks and best regards.

Is this only seen with using appsrc or can this be replicated with filesrc as well?

Are you outputting to a display? If so, can this be seen with outputting to filesink?

hello,

We may have found the problem, maybe because our current settings only have one I-frame at the beginning. Later, we modified it to 300 frames and added an I-frame. The problem seems to have subsided, and we will continue to test it again

Thanks and best regards.

Sounds good, let me know if you need any help modifying I-frame or IDR-frame period. If your problem, is resolved please mark the ticket as resolved.

Thank you,
Sarabesh S.
