ffmpeg - error processing files generated by premier pro 2022
23 mai 2022, par QRrabbitPlease help with the error, trying to re-encode the source file produced with prores 4444+alpha. Alpha channel is required in my case.


I've tried two separate options, both are erroring out :


$ ffmpeg -i Input.mxf -vcodec prores_ks -profile:v 4 -y Output.mxf 



I'm getting this output

FFMPEG : Youtube streaming issues
23 février 2019, par Alex ParamonovI am trying to make a reliable stream from my Icecast/Shoutcast servers to Youtube live.
The command that I use is :/usr/bin/ffmpeg -re -loop 1 -framerate 1 -i /var/users/youtube_stream/DJ-philadelphia_jO46wsH.jpg -i http://127.0.0.1:4700/radio -c:v libx264 -preset ultrafast -maxrate 2048k -bufsize 2048k -c:a copy -ab 128k -s 1920x1080 -rtmp_live live -f flv rtmp://a.rtmp.youtube.com/live2/k123 -nostats
The stream starts running but suddenly stops at random times with the output similar to this :
av_interleaved_write_frame(): Broken pipe
[flv @ 0x5641e04db260] Failed to update header with correct duration.
[flv @ 0x5641e04db260] Failed to update header with correct filesize.
Error writing trailer of rtmp://a.rtmp.youtube.com/live2/123: Broken pipe
frame= 4771 fps=1.0 q=2.0 Lsize= 106465kB time=01:19:30.00 bitrate= 182.8kbits/s speed= 1x
video:29022kB audio:74516kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead: 2.825971%
Conversion failed!
99%
Exiting normally, received signal 15.I can’t say exactly why is this happening and maybe there is a way to fix it, but to mee it looks like ffmpeg can not send or convert some frame and it breaks the entire process, so I started digging the docs and found a
fifo
format that hasreconnection
options in case of failure.
So my new command is :/usr/bin/ffmpeg -re -loop 1 -framerate 1 -i /var/users/youtube_stream/DJ-philadelphia_jO46wsH.jpg -i http://127.0.0.1:4700/radio -c:v libx264 -preset ultrafast -maxrate 2048k -bufsize 2048k -c:a copy -ab 128k -s 1920x1080 -rtmp_live live -f fifo -fifo_format flv -map 0:v -map 1:a -drop_pkts_on_overflow 1 -attempt_recovery 1 -recovery_wait_time 1 rtmp://a.rtmp.youtube.com/live2/123 -nostats
With this command Youtube starts complaining about video resolution saying that
65535x65535
is not supported, value65535
looks like something is not initialized properly. Please note that I have explicitly set the resolution with-s 1920x1080
.The output from
FLV
andFIFO
formats looks quite similar.FLV
