[Balling]

Where is the file?

[charlymp]

Replying to Balling:

Where is the file?

I edited the ticket

[Balling]

Yeah. I confirm it all including h264_cuvid part. -hwaccel does not help either as you can see in mpv... I also cannot -c copy it! Wow.

[James]

The sample has no IDR frames, so you need to use -flags2 +showall to signal the decoder to output frames even if no keyframe has shown up.

And to do codec copy, you need to use -copyinkf for the same purpose.

[Balling]

How is #8820 related to this? Also again that PES problem.

[Balling]

The sample has no IDR frames

That is not needed: IDR frames are not the only keyframes. Just recovery point SEI frame is enough.
