ffmpeg exit after few minutes capturing from USB HDMI capture

[giuliano]

Hi,
I'm trying to get the live feed from an USB HDMI capture.

Here follows the ffmpeg command I'm using
ffmpeg -f alsa -thread_queue_size 1024 -i hw:1 -f v4l2 -i /dev/video2 -codec:v libx264 -b:v 2000k -preset ultrafast -level 4.0 -crf 22 -r 25 -vf scale=1280:720 -threads 0 -acodec aac -b:a 92k -ac 2 -bsf:a aac_adtstoasc -f flv rtmp://prg-1.s.cdn77.com:1936/1341229128/34567

and attached find the ffmpeg log file (ffmpeg.log).

The streaming works fine but after few minutes ffmpeg exit (see the ffmpeg log file) printing:
"Exiting normally, received signal 15."

I tried to capture only the video or only the audio or using as output a file
but I got always the same result, after few minutes the ffmpeg command exit printing:
"Exiting normally, received signal 15."

What I can do to avoid the ffmpeg command to exit?
Do you need some more info to investigate this issue?

Best regards

Hi,
one more comment:
in the above scenario, VLC works fine setting as video and audio device
/dev/video2 and hw:1.

Hi,
one more information:
ffmpeg exit after about a couple of minutes also in case of capture a webcam

So it seems it is a "general" capture issue and not related to the USB HDMI capture!!!

Are you seeing an issue with rtmp output or USB input?

[giuliano]

hi,
it is an issue on input, ffmpeg stops capturing after 1-2 minutes
independently if the output is an rtmp or a file.

I have the same issue on both inputs: USB and also the integrated camera/mic.

VLC, using the same USB devices, /dev/video2 and hw:1, works fine.

Let me know how I can help you to find out the issue.
Best regards
