ffmpeg error when I try to stream on trovo

Question

When I try to start a stream on the trovo, the error av_interleaved_write_frame(): Unknown error appears.

comand:

ffmpeg -i D:\voi.mp4 -c copy -f flv rtmp://livepush.trovo.live/live/<key>

output:

I guess this is a problem on the part of trovo. I mean, it is possible that certain restrictions must be observed for streaming on this site, but I do not know which ones specifically. So how can I fix this?

PS on other platforms the stream works for example twitch.

I have tried many commands and different video formats, the result is the same.

Answer 1

I found a solution. You need to specify the video codec -vcodec libx264 .

this git helped me:Trovo live streaming

The minimum command to run looks like this: ffmpeg -i "D:\voi.mp4" -vcodec libx264 -f flv "rtmp://livepush.trovo.live/live/<key>"
