[FFmpeg-user] IP Camera Stream "Conversion failed!" from newer ffmpeg instance, but not from older?

[Steven Kan]

I normally stream my IP cameras to YouTube from my RPi. I just got my spiffy new (used) M1-based Mac mini, so I’m trying to move my streams over there so I can use the extra horsepower to stream 2-up from 2 cameras into one stream. 

But first I want to just duplicate what I’m doing on the RPi before I break it ;-)

I copied the exact same ffmpeg command:

./ffmpeg -thread_queue_size 1024 -rtsp_transport tcp -i "rtsp://anonymous:password@192.168.1.50:554" -vcodec copy -acodec copy -t 01:47:02 -f flv "rtmp://a.rtmp.youtube.com/live2/<my-youtube-streaming-key>"

over from my RPi to my Mini, and it fails with "Conversion failed!”. Ordinarily I’d be inclined to update my software, but the version that works on my RPi is _older_ than the one on the M1 Mini that fails.

Do I need to add a missing library?

Thanks!

Working command from RPi:

./ffmpeg -thread_queue_size 1024 -rtsp_transport tcp -i "rtsp://anonymous:password@192.168.1.50:554" -vcodec copy -acodec copy -t 01:47:02 -f flv "rtmp://a.rtmp.youtube.com/live2/<my-youtube-streaming-key>"
