Hi,
I am trying to figure out the H264 throughput speed of livemedia library. As
I know, the library uses durationInMicroseconds in
H264FUAFragmenter::afterGettingFrame, which finally passes the value to
MultiFramedRTPSink::sendPacketIfNecessary() to determine the when to send
next frame.

Hi Ross,
Thanks for your explanations. I am somehow unsure about the proper setup of
fPresentationTime and fDurationInMicroseconds.
My h264 video stream comes in the oder of pps, sps, I, P, P, P...(29 times)
in a second.
Is the following code correct ? Thank you.
::continueReadProcessing() {
Hi All,
I need to understand the value of fPresentationTime fDurationInMicroseconds.
Those two are used in almost all videoframers.
I have an IP camera, which sends out video frames in the oder of pps, sps,
I, P, P, P...(29 times) in a second. So should the fPresentationTime/
fDurationInMicroseco
Hi,
I want to add some use private data (like camera locations, etc)
periodically to H264 video stream. This rate of these private data is very
slow, like 10Kbps.
One way (A) is to create a separate "faked" video stream for the
transmission using libmedia's rtp/rtsp library. Since rtp/rtsp does no
Hi,
I have an architecture question of livemedia. Livemedia is a single thread
program, it uses "event" to serve multiple video streams.
If in one video stream, I called some blocking functions, will it hurt other
video streams?
For example, assume the server wants to server two video streams, A a
Russ,
Thanks for your reply. I am very sure the fPresentationTime is correct.
I can use VLC to play the RTSP stream for 2 , 3 minutes correctly, then
suddenly VLC becomes blank.
Because openRTSP has the buffer limitation (encoded frame must be able to
fit into the buffer, I set it -b 60K),
I suspe
Hi,
I have made a H264 media server and the input is encoded frames directed
coming from the hardware encoder, not from a file.
I can successfully receive the H264 stream from openRTSP command tool and
store the received stream into a file.
The VLC player also can play the stored the file smoothly
Hi,
I play to live stream h264, the source is not a file, but encoded
video frames from hardware. Can some one suggest what example code I
can look at as reference, like H264VideoStreamFrame,
VideoFileServerMediaSubsession (their source is a file , not encoded
frames)?
Thanks a lot.
Best Regards,
Hi,
I write a H264 framer and it works with openRTSP. However, it will
cause VLC player to crash.
Thanks for Ross's comment, I realized that my setup of SDP
sprop_parameter_sets_str is not correct.
I do not know the format or structure of SDP sprop_parameter_sets. I
go over the RFC 3984, but not
Hi,
I am working on a H264 video framer to stream a h264 file. I did some
search on the forum and found Mike did some solid work before.
Basically, I wrote a H264 videostream class, which are almost a
re-make of Mike's work. However, I have problems to play the stream on
VLC. The VLC player will c
