Is there a fix for this or a workaround to cast flash(mostly) videos?
There are generally two reasons you'll see buffering/stuttering when casting a tab or the entire desktop
- The audio/video isn't getting from your computer to Chromecast fast enough
- Your computer isn't fast enough to provide the audio/video to Chromecast in real-time
Tab and desktop casting essentially requires the computer to
- Receive the content from the Internet (load on network)
- Display/decode the content (load on CPU)
- Encode the content into a Chromecast-friendly format (load on CPU)
- Send the encoded content to Chromecast (load on network)
So, if your computer is too busy decoding the content and not enough CPU time is available to encode it to a Chromecast-friendly format, you will get buffer/stutter.
Likewise, if your computer's network connection cannot sustain the download of content from Internet and send of the recompressed content to Chromecast in real-time, you will get buffer/stutter.
Since it sounds like you're viewing Flash video content, make sure Hardware Acceleration is enabled - that should reduce the CPU load when Flash stuff is displaying.
Also note that the "recompress to Chromecast-friendly format" does not seem to be parallelized much, if at all, so a faster single or dual-core suste, will likely do better than a slower multi-core system.
