I'm trying to create a rtsp server to stream MJPEG images.
Ugh. JPEG is a *terrible* codec for video streaming.
I have implemented a new TestJPEGFileServerMediaSubsession that
creates a TestJPEGVideoRTPSink.
In TestJPEGVideoRTPSink::doSpecialFrameHandling I'm adding the
quantization tables of the image into the header
using setSpecialHeaderBytes
Note that the existing "JPEGVideoRTPSink" code already does this.
You should not have to reinvent the wheel here.
This is working fine using some JPEG images, but fails with others.
I'm testing one image that has the marker 0xFF, 0xDD ( Define
Restart Interval) and I think I have to do something else seeing
this comment in the code
// Note: We assume that there are no 'restart markers'
So, what should I do with images containing restart markers and macroblocks?
The JPEG transmitting code ("JPEGVideoSource" and "JPEGVideoRTPSink")
currently don't support "Restart Marker Headers" (see RFC 2435,
section 3.1.7). You will need to update the (definition and
implementation) of these two classes to support them.
