[FFmpeg-user] UDP streaming to Pico QAM modulator

[Steve Kowald]

Hi  Carl,

Sorry, I re-ran using FFMPEG -i for both FFMPEG streaming and Lead Tools streaming
of the same file. It looks like LeadTools might be re-encoding the audio to 384K because
it is only 224K in the encoded file.

To stream the file using FFMPEG I used the CLI:

ffmpeg -i "c:\Superman vs Batman.mpg" -f mpegts udp://192.168.1.3:10005?pkt_size=1316

This is the output from FFMPEG -i  on that stream:

This is the output from FFMPEG -i  when using LeadTools to stream the same file:
