Max Bitrates relation to buffer size:
Is there are relation? how do they relate? should a given max rate have any specific type of buffer amount?
Is a buffer needed when setting max bitrate anyway? Is buffer only related to streaming over networks?
Edit: opps should have posted this in Devices... please move mods...

Re: Max Bitrates relation to buffer size
Im still not understanding how buffer affects things.
Right now Ive figured that my Mac Mini 1.83ghz running Plex (.13) can handle around a MAX/Peak bitrate of 30mps.
So ive capped it vbv-maxrate=26000 and a bufsize=5000 and Ive set the average bitrate to 20000
Can someone that knows... explain what ive done here? lol and if this is a good idea/setting
Thank you

Re: Max Bitrates relation to buffer size
Have a look at the logs above. They're a bit technical (I don't fully understand them), but there's a lot of precise info about this feature…
Re: Max Bitrates relation to buffer size
Yes, thank for posting the link rodeo. I did read some of it. was looking for someone to expand on my follow up. thanks though...
Re: Max Bitrates relation to buffer size
Well, for how long ? a vbv buffer has to have a specified length. this has to be known to determine if you're settings make any sense.peter893 wrote:Im still not understanding how buffer affects things.

How long? you mean the length/time of the movie? can you type in an example?dynaflash wrote: Well, for how long ? a vbv buffer has to have a specified length. this has to be known to determine if you're settings make any sense.

Re: Max Bitrates relation to buffer size
well, as the docs you were linked to explain, a video buffer has a size and a length. Not the length of the movie, but the specified length of the devices video buffer. You would get this from the specs or from *alot* of empiricle testing. Video buffer length might be .5 seconds, or one second or ??? basically you do not have enough info about the target video buffer to determine if your settings are sane or not. Its much more complicated than it looks.
Re: Max Bitrates relation to buffer size
I Did read the link, but I guess I didnt understand.
So the playback devices/softwares working buffer = the buffsize?
I have had no issue with the moveis Ive done with setting above... what would be some issues if incorrect bufsize was set?
