[FFmpeg-user] UDP Packet size option

[Damian Głodny]

Hey, verify packets size with Wireshark.
You can also add -flush_packets 0, to be sure that all packets will have
1316 bytes.

Subject: [FFmpeg-user] UDP Packet size option

Hi,

I've been trying to get my decoder to read my UDP feed but for some odd
reason it doesn't like when I add the ?pkt_size=1316 option to my unicast
stream.

>From reading around I am aware that I can recompile ffmpeg with a custom MTU
setting to ensure I can get the desired packet size, however my question is
if there is another way to insert the MTU override setting in the CLI
without placing it right at the end of the stream?

Command is:

ffmpeg -re -i rtmp://x -vcodec mpeg2video -r 25 -flags cgop+ilme
-sc_threshold 1000000000 -b:v 2M -minrate:v 2M -maxrate:v 2M -bufsize:v 0.2M
-muxrate 2.5M -acodec mp2 -ac 2 -b:a 224k -f mpegts udp://
192.168.0.4:1234?pkt_size=1316

Thanks in advance.
