Intermittent viewing issue on Raspberry Pi 3B+

[mpv1953]

Hello: Yes, the title is vague because I'm not what the problem is. I installed the program on an RPi 3B+ running Buster. It works, but every few seconds (ranges from 15 seconds to about two minutes) my monitor screen goes blank. Sometimes, the "normal" level logging shows: root@pisc04:/tmp#` 'root@pisc04:/tmp# tail -500f v4l2rtsp_201005_1300.log' `log level:500 And others, it's this: log level:500 AddH26xMarkerFilter::afterGettingFrame(): buffer too small truncated:5771 bufferSize:205744 MPEG2TransportStreamFromESSource: input buffer too small; increase "MPEG2TransportStreamFromESSource::maxInputESFrameSize" by at least 5771 bytes! AddH26xMarkerFilter::afterGettingFrame(): buffer too small truncated:5473 bufferSize:205446 MPEG2TransportStreamFromESSource: input buffer too small; increase "MPEG2TransportStreamFromESSource::maxInputESFrameSize" by at least 5473 bytes! AddH26xMarkerFilter::afterGettingFrame(): buffer too small truncated:4115 bufferSize:204088 MPEG2TransportStreamFromESSource: input buffer too small; increase "MPEG2TransportStreamFromESSource::maxInputESFrameSize" by at least 4115 bytes!

The build was successful. I run the application with this script: `root@pisc04:/usr/local/bin# cat runsc.sh #!/bin/bash

I use this camera for exterior home monitoring, and it's aggravating to have the screen go blank, which is usually when there's something interesting. You can see from the script that I've been trying different options, but none seem to work.

Do you have any suggestions/recommendations? Thanks, MIke

Sorry about the formatting. I don't know why it did that.

Having the same issue here, did you find a fix @mpv1953 ?

[mpv1953]

Hi @biodrone: No I did not. I switched gears and went with local recording instead of using a web browser. Cheers, MIke

Hi,

MPEG2TransportStreamFromESSource::maxInputESFrameSize is set to 100000. If you have bigger image, you can try to increase it.

Best Regards, Michel.

Hi Michel,

Thanks for the follow up! I'm using the docker container, is there a flag to pass to change this parameter or will I have to compile it myself?

Thanks, Josh
