Can not stream with resolution if greater than 320x240 MediaRecorder(12959): start failed: -2147483648

[Sky-Zheng]

I use libstreaming for a server, and play in vlc, but find it can work at 320x240, but can not work when resolution greater than 320x240,

this is the error info

Hi, have you solved this problem?

[manu3b1]

Got the same issue.
In the full log, I can see:

E MPEG4Writer: cannot seek mFd: Illegal seek (29) 7

So, I guess the new MPEG4Writer is no more compliant with pipe FD.

I'm sure I'm way to late to the party, but I think the reason for this "no more than 320 x 240" is here

libstreaming/src/net/majorkernelpanic/streaming/video/H264Stream.java

Line 125 in 3a78d22

if (mQuality.resX>=640) {

I commented out the fallback and was able to stream at higher rates.
