I need capture a udp stream, I describe the issue with below mentioned two
cases, please let me know how this issue can be resolved?
Regards
Ajay
===============================================================================
Case1)
When I executed following command
"ffmpeg -i udp://226.0.0.1:1234 -map 0:v:1 -map 0:a:0 -acodec copy -f mp4
2609_5v.ts"
It says "Circular buffer overrun. To avoid, increase fifo_size URL option. To
survive in such case, use overrun_nonfatal option"
Original total video length 64 second but it generates only 40 second video ,
good part is this 40 second is playable.
==================================================================================
Case2)
Then I start using fifo_size option and executed below command
ffmpeg -i 'udp://226.0.0.1:1234?fifo_size=875000&overrun_nonfatal=1' -map 0:v:1
-map 0:a:0 -acodec copy -f mp4 2609_5v.ts
In this case it did not complain circular buffer overrun but after complete
processing ffmpeg hangs itself , I waited a lot then I need to terminate this
ffmpeg.
Output file generated by this case is not playable?
Below are the complete logs
ffmpeg -i 'udp://226.0.0.1:1234?fifo_size=875000&overrun_nonfatal=1' -map 0:v:1
-map 0:a:0 -acodec copy -f mp4 2609_5v.ts
