Will do some tests...thx for your input, @DieBagger and @FreakyJ

Here are the results of the german jury (for a 6.02 minutes SD-recording; attention: there is probably overhead included too):

Flash Ultra Low Quality: 39,16 MiB -> ~ 110 KiB/s
Flash Low Quality: 54,31 MiB -> ~ 153 KiB/s
Flash Medium: 63,75 MiB -> ~ 180 KiB/s
Flash High Quality: 90,49 MiB -> ~255 KiB/s

I have given up after this test since my CPU isn’t powerful enough…but I think it might be useful for others users…

The problem with predicting bandwidth usage is that it should theoretically be equal to the video bitrate + the audio bitrate, but it isn't even close in most cases. This might be due to encoder inefficiencies with VBR and it might work better with steady material instead of material with a lot of action, but I've no clue why the difference is so big.

So testing it is really the only good option, most of the time.

I did my own measurements by using Resource Monitor but came nowhere close to The_Stig's numbers. I guess more bandwidth is needed to stream over the internet though..

Im afraid it's needed a lot of bandwidth. I've a 2mbits upload/6 Mbits download connexion and I cant use any of the flash or http formats. For some reason the bandwidth required is much more than expected. My playback stops every 10-15 sec to buffer. I use i5 3570 ivy bridge processor that can handle various sd channels simultaneously on local network but not thought Internet.
For the testin i use same quality Than the comertial Spanish TVE channel with 576x324 vbr around 800 kbps that brings good quality flash and can be play with low Internet speed like 500 Kbps or less. Ours mpextended takes my full 2Mbps. Making impossible to stream over Internet regardless of the quality...

Imho its not too much of difference between our results. Could be - as @Oxan said - due to material.

@alexdepalma, what I have recognized during my tests is that my bandwith is maxed out for a certain time and then going down significantly. This means MPExtented is trying to stream the whole content. But I tested only with a recording, not with LiveTV.

Yes, but only in WebMP... aMPdroid only buffers a certain amount of time... This is something we want to change in WebMP too but it requires changes to the web player.
