[FFmpeg-user] Nut + ZMQ + rawvideo

[Online video]

Hi,


I want to distribute uncompressed video to multiple separate processes
using Nut format and ZMQ protocol.


The first distributing process works for me without problems:

*c:\ff\ffmpeg.exe -i "source_link" -c:v rawvideo -c:a pcm_s16le -f nut
"zmq:tcp://127.0.0.1:11111 <http://127.0.0.1:11111/>"*

But I cannot accept this stream, the receiving process does not start:

*\ffmpeg.exe  -f nut -i "zmq:tcp://127.0.0.1:11111
<http://127.0.0.1:11111/>" -c:v libx264 -preset:v fast -b:v 8000k -maxrate
8000k -bufsize 8000k -bf 2 -g 50 -keyint_min 50 -c:a aac -b:a 128k -f
mpegts "udp://127.0.0.1:22222?pkt_size=1316
<http://127.0.0.1:22222/?pkt_size=1316>"*

After press CTRL-C:

What can you advise to solve this problem? Perhaps, instead of NUT, there
is another container format that allows you to transfer uncompressed
streaming video to multiple recipients?


If I pass such a stream through a pipe using the same commands, then
everything is ok, it works:

*\ffmpeg.exe -i "source_link" -c:v rawvideo -c:a pcm_s16le -f nut - |
\ffmpeg.exe -f nut -i - -c:v libx264 -preset:v fast -b:v 8000k -maxrate
8000k -bufsize 8000k -bf 2 -g 50 -keyint_min 50 *
*-c:a aac -b:a 128k -f mpegts "udp://127.0.0.1:22222?pkt_size=1316
<http://127.0.0.1:22222/?pkt_size=1316>"*
