[FFmpeg-user] Error decoding RTSP stream using h264_cuvid vcodec

[Nishant Trivedi]

Oh duh! Thanks @Moritz!

As a side note, I just wanted to mention that we mostly deal with RTMP
streams and we have been starting the ffmpeg process the way I described
for over a year and half now and it never complained. It's just now that we
started looking into supporting RTSP, ffmpeg complained about the option.
Obviously it's a bug on our end and we will fix the arg but I thought it
would be interesting to note the behaviour here. Thanks again!

Best,
- Nishant.
