When I recoding UDP stream with segment command, the log displays the following message:
Circular buffer overrun. To avoid, increase fifo_size URL option. To survive in such case, use overrun_nonfatal option The machine configuration: Intel (R) Xeon (R) CPU E5620 @2.40GHz 2.39 GHz 16.0G Memory x64 Windows Server 2008 R2 Enterprise The command I used is: ffmpeg -y -i "udp://@225.1.2.2:6002?overrun_nonfatal=1" -t 24:00:00 -qcale:v 2 -alternate_scan 1 -f segment -segment_time 01:00:00 M:\\shoulu\\%04d.mxf" There is a crash occured when the command tried to "segment" after running about 1 hour. In addition, after I specify the fifo_size value by fifo_size=50000000, the crash disappeared. And if I set fifo_size=500000000, the ffmpeg will crash when it starts. Why does the problem occur? Anyone can explain the function of fifo_size? _______________________________________________ ffmpeg-user mailing list [email protected] https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
