Hello,
I am reading out different MXF testfiles with different codecs with
ffprobe/ffmpeg
The container is always MXF Operation Pattern 1a, and the codecs are:
XDCAMHD422, AVC-Intra, DNxHD and MPEG-IMX50.
The filelength of every file is 10 seconds.
ffprobe gives me following (yellow) hint at 6 of 8 AVC-Intra MXFs:
[mxf @ 0000000002a984e0] Stream #0: not enough frames to estimate rate;
consider increasing probesize
The other codec samples are ok. (DNxHD, XDCAM, IMX50)
What is missing in these MXF containers (header) when this hint message
appears?
Best Regards
Christoph
