Fix for transtreamproxy high CPU usage in BH 2.1.1

[EnF70]

If you are bothered by the high CPU usage in BH 2.1.1 while transcoding and streaming you can try this file. Install manually by replacing the existing file "/usr/bin/transtreamproxy".

I don't have any contacts in the Vu+ dev team, if you know someone PM me so I can send them the fix.
(patch file containing the fix is attached).

Thank you! Tested it on the latest Vix and I am seeing less than 2% CPU. Cheers!

Thanks, I have reported the bug.

 

[EnF70]

Made a couple of more changes:
- changed retry count to 3 to improve file seek when transcoding
- changed logic to move data between input and output only if output is ready for writing (both threads)
- moved logic to stop transcoder in the source (encoder) thread as the stream thread blocks during write

Hopefully the transcoder will be more stable now.
Please report if you still find transtreamproxy process hanging with 99% CPU usage.

Found a small code issue (misplaced curly bracket) in the last version which was causing the transcoder to stop.
Use this version:

HI how to use pathch file?

 

[Finbarr Brady]

You don't need to download that file unless you want to look at the source code changes.

T.U very much

The latest patch doesn't load video for me at all in VLC using the default transcoding settings on VIX. It does however, work on my iOS device.

Media info from VLC attached.

 

[Finbarr Brady]

Ok weird. This is also happening in VLC even when I revert to the original transtreamproxy. Mmm

 

[Finbarr Brady]

Problem was on my end. I was messing with Openwebif streaming code. Ignore me.
