Comment:

 This is actually an issue with the way the web server receiving the
 `-progress` URL is configured.

 ffmpeg is sending the progress data as it happens, using a chunked `POST`
 body.

 You can test this with netcat; use the netcat url as the destination for
 the `-progress` option:


 {{{
 # start "server"
 nc -l 7000 > ffmpeg.http.log &

 # render 30 seconds of blank h264 sending progress to the server
 ffmpeg -y -progress http://127.0.0.1:7000 -t 30 -f lavfi -i
 color=c=black:s=640x480 -c:v libx264 -tune stillimage -pix_fmt yuv420p
 black.mp4

 # cat the "server" log
 cat ffmpeg.http.log
 }}}


 You'll see the chunked POST headers, followed by the data:


 {{{
