Hi
I refered to wis-streamer code which implements a FramedSource
for go7007 tv-tuner
I am using the live & wis-streamer on Windows XP service pack 2
I am attempting to build a Windows DirectShow filter which
feeds video / audio frames to a custom
FramedSource which implements the readfile() which in turn gets
framedata from the DirectShow filter
I am feeding my Filter from Microsoft MPEG-4 VKI Codec V3
( Output PIn shows type as MP43)
Even though I recve the data in Framed Source , when I connect
using VLC nothing happens
Please I need some help in understanding - what format the
frams should be fed using Framed Source ? Should be in Raw or any
specific codec ?
I would say the format of the frames your FramedSource should deliver
depends on which Framer you use.
I've made a subclass of FramedSource which encodes MPEG4V frames
using Ffmpeg in the doGetNextFrame function. It feeds it frames to an
MPEG4ESVideoRTPSink and from then on i did about the same as in the
testMPEG4VideoStreamer test program.
in short:
RTPSink* videoSink = MPEG4ESVideoRTPSink::createNew
(*live555usageEnvironment, rtpGroupsock, 96);
MySubclassFramedSource* liveVideoSource =
MySubclassFramedSource::createNew(*live555usageEnvironment); //
encodes the frames using FFMpeg
MPEG4VideoStreamFramer *videoFramer =
MPEG4VideoStreamFramer::createNew(*live555usageEnvironment,
live555VideoSource);
videoSink->startPlaying(*videoFramer, live555AfterPlayingFunc, NULL /
*clientData*/);
Looking forward to any kind of support
Thanks in advance
Sanath
