NEW POST: Strange Video Colours on XBox

david4482 — Wed, 07 May 2008 14:11:45 GMT

When I run any videos on the XBOX with scurvy media, even the small example video provided, the colours appear like they were encoded wrong (Vibrant strange colours show). Any ideas?Works perfect on PC.
This happens when using compression on or off. Tested with playback type stream. Encoded some other videos with cvid format with no compression and got same result.

NEW POST: Exception in VideoStreamGetFrameOpen

you know what, I think I figured out what the problem is. Currently, the .avi file that you add to the project must be writable. Please check to see whether the file has the readonly flag enabled, and if so, remove it and try it again.

UPDATED WIKI: VideoContentManager

This specialized content manager is required for video streams because it will lock the file stream open so that the video class can stream off disk while the movie is playing.

UPDATED WIKI: AviImporter

The AVI Importer is using an ever so slightly modified version of the AVIFile wrapper located at codeplex:
http://www.codeproject.com/KB/audio-video/avifilewrapper.aspx

Future versions of the avi importer may or may not continue using this API, but end users will not be affected.

NEW POST: Requirements Avi movie

joelmartinez — Mon, 28 Apr 2008 08:45:28 GMT

In theory, the only requirements are that you have the codec installed on your dev machine so that the content pipeline can decode the frame data. Also, currently, there's a known issue where the .avi file must be writable.

Beneath the hood, I'm using a slightly modified AVIFile wrapper that can be found here http://www.codeproject.com/KB/audio-video/avifilewrapper.aspx.

I have tried it with a divx movie, but i got an error. Than i tried it with a converted avi movie and this didnt work either.

What error did you get? would you mind sending me the video so I can try to debug it locally? you can send it to joelmartinez@gmail.com

COMMENTED ISSUE: File Streamed videos may play too fast or too slow

joelmartinez — Mon, 28 Apr 2008 08:31:01 GMT

Right now, the streaming video doesn't take into account the timed frame index that the base Video class calculates for you, it just plays the next frame every update. Thus, if the game's framerate is too fast or too slow, the video will play accordingly.

-Need to store in the .xnb the frame index right before the actual texture.
-Modify the runtime class so that if the just-loaded frame index has already passed, it will advance to the next one until it catches up.

looking at this one now.

COMMENTED ISSUE: AVI must be writable

joelmartinez — Mon, 28 Apr 2008 08:29:55 GMT

input AVIs must be writable for the import process to work. This is despite the fact that the import process only reads and does not change any details on the AVI.
Comments: ** Comment from web user: joelmartinez **

I am planning on changing the tech used to decode the AVIs to use something else. Still investigating that, thus, this issue is deferred for right now.

Mon, 28 Apr 2008 02:20:36 GMT

*Xbox 360 Project support!
*Streaming playback mode is now multithreaded. On xbox, it defaults to Core#2.
*Texture setting is now double-buffered to avoid stalls and further improve performance.
*Internal video related functionality has been moved to the Scurvy.Media.VideoModel namespace.
*Fixed InvalidOperationException bug. This a side effect of the double buffering above :-)
*Improved runtime allocation profile by removing debug write statements.
