operating system – Camera Rendering Buffers and Stutters When Large Video Files Being Processd with FFmpeg

When rendering a real-time camera, I use ffmpeg to process a large video file(like 4G or even larger) at the same time. I noticed that the video frames are buffering and stuttering.

Pipeline:

DISPLAY=:0 gst-launch-1.0 filesrc location=/home/user/jellyfish-120-mbps-4k-uhd-hevc-10bit.mkv ! matroskademux name=demux demux.video_0 ! queue ! h265parse ! nvv4l2decoder ! nvvidconv ! xvimagesink

FFmpeg command:

ffmpeg -i ${file_name} -c copy -f segment -segment_time 600 -segment_format_options movflags=+faststart -reset_timestamps 1 ./${file_name}_%02d.mp4 -y

And there are some warning indicated that “a lot of buffers are being dropped” duration stuttering.

The requirement can be summarized as “real-time video rendering has higher priority, and the low rate of large file processing is accepted”, are there any possible solutions of this issue from your perspective? Thanks in advance.
