[anrayliu]

Here are a list of known bugs as of version 0.9.25.

• yt-dlp release v2024.12.23 is bugged and sometimes causes youtube videos to fail to open. Upgrade to the latest version to fix.
• Youtube videos can ocassionaly freeze or stutter due to slow frame grabbing over the network.
• Seeking in some Youtube videos seem to fail at 1080p.
• Some videos, due to how they were encoded, cannot their frame count extracted with 100% accuracy. The extracted number usually differs from the real number by a few frames. If a completely accurate count is required, use video._get_real_frame_count() or preload the frames.
• Some videos when played as bytes cannot have their frame size read properly. This will cause an exception.
• Some videos when played as bytes cannot have their frame time stamps extracted, which means VFR videos cannot be read as bytes.
• PyAV version 14.0.1 seems to cause bugs in imageIO for now. Use decord to read from bytes for the time being or downgrade to version 13.
• When using the decord reader to play a video with multiple video tracks, the first track will not be selected, causing side effects and potential exceptions. Use any of the other three readers instead.
