Add tcp option

[ehsan-elwan]

I have an ffmpeg that forward a local udp stream to a remote server using this command:
ffmpeg -loglevel level+warning -n -progress tcp://127.0.0.1:62012 -fflags +genpts -fflags +nofillin -fflags +discardcorrupt -i udp://127.0.0.1:1651?reuse=1&overrun_nonfatal=1&fifo_size=50000000&buffer_size=20000000 -c:v copy -c:a copy -f flv rtmp://stream-source.abc.com:1935/live/streamcam10

I'm able to generate the above command with the ffmpeg wrapper, but the command fail due to TCP negotiation failed

I found that I need to add a tcp option to make it work like so:
ffmpeg -loglevel level+warning -n -progress tcp://127.0.0.1:62012\?listen=2

The above command works but I'm trying to away to add the listen option to tcp but I can't find away to set it up in the wrapper any help is much appreciated

Probably, you specified ?listen=2 at wrong option. -progress tells ffmpeg where to send progress reports, and this port is opened by Jaffree itself.
Please, provide code sample and logs. Issue template clearly says that it should be provided.
