That is, with a command line of "ffmpeg.exe -i -f null -". The RTSP stream decodes successfully without any hardware acceleration. The same command line successfully decodes using an mp4 file instead of an RTSP input (captured from the camera using ffmpeg -i -acodec copy -vcodec copy c:/abc.mp4) When running, it initializes the connection to the RTSP server and then logs an errorĮrror initializing the MFX video decoder: invalid video parameters (-15) I suspect the reproduction of this problem requires a genuine RTSP server.
If there is a way to capture this stream such that someone else can reproduce the error, please let me know.
It looks like it has a pixel format of 720x576, pix_fmt: yuvj420p. Running on Windows 10 with an Intel GPU (Intel UHD Graphics 620, but I suspect this problem isn't related to the exact hardware version - it also reproduced on another machine).
(Windows version)įfmpeg.exe -init_hw_device qsv:hw,child_device_type=d3d11va -hwaccel qsv -c:v h264_qsv -hwaccel_output_format qsv -i -f null. Using ffmpeg version: ffmpeg version 5.0.1-full_build from () built on.
