Yes, I'm really wondering why I only have this issue with the HEVC bitstream. h264, av1, mpeg2, mjpeg, vp9 ... they're all fine.
Do you know if anything has been changed with the latest version? ________________________________ Von: Libav-user <[email protected]> im Auftrag von Wang, Fei W <[email protected]> Gesendet: Dienstag, 2.

You may need check why it leaks IDR frame. On Mon, 2024-07-01 at 19:06 +0000, Daniel Stankewitz wrote: No, I only have this issue with the HEVC bitstream.

Can you share a encoded bitstream by your app?

When I exported a video with a length of min. 6 minutes and I play it with i.e. MPC-HC I experience a long seek time when jumping through the video. The later the point I seek to, the longer it takes. Just like it has to crawl through the whole file until it finds the right frame. This didn't happen with libav* from FFmpeg 6. It also doesn't happen when using the FFmpeg 6 or 7 CLI, only when I encode a file using libav*. Does anybody have any idea what this could be?
