In program (UI) everything works fine.

p.s. why you make all parameters for ffmpeg in quotes “” ?

2

Did you set the environment variables?
The reason they add all the quotes is to reduce potential errors over different operating systems. For example in Windows: a path with no spaces will work fine with no quotation marks, but once a space is added, it breaks.

3

Its easier to check if parameter (path) contains space - before adding quotes.

4

Depends on how you’re generating the command. In the Python script I made to generate commands for TVAI, I found that spaces were a pain-point more than three times—and I only tested it on Windows. It probably doesn’t work on Mac.

Hello,

Could you share the last message from ffmpeg before the command fails? The [swscaler @ 000001EA1DA00040] [swscaler @ 000001EA1DB24180] No accelerated colorspace conversion found from yuv420p to rgb48le. message is expected when using the CLI and is just an informational line that does not stop the process from running.

Thanks!

Tested in 3.2.1 and now no such error anymore. Works fine from any command prompt.
