I mean:
when player's system uptime is 100, it play a video frame and an audio sample whose NTP is 80.
the video frame and the audio sample whose NTP is 90 will be played when play's system uptime is 110, Is this right?

thanks for your help!

I respect your work, Thanks very much!

another question:
If user select one of the audio streams, VLC will just decode the selected audio stream, not decode the others.Is this right?

If SDP has one video stream and two audio streams in different language, VLC will setup for three streams. for example: Client->Server: Setup rtsp://audio.example.com/twister/video RTSP/1.0 Server->client: RTSP/1.0 200 Ok Client->Server: Setup rtsp://audio.example.com/twister/audio.en RTSP/1.0 Serve...

Can you give me an example, how to use the system uptime, and the NTP? Precondition: Player's system uptime is 100,the frequency is 1. Three Video Frames, their NTP is 80,90,100. Five Audio Samples, their NTP is 80,85, 90,95,100. Conclusion: system uptime:? the Video output:? the audio output:? thin...

The reply is helpful, Thanks！ the real-time clock is the system clock of the player, is it? does VLC use gettimeofday() as the real-time clock? in 13818-1, the end-to-end delay from the signal input to an encoder to the signal output from a decoder is a constant. This delay is the sum of encoding, e...

Thanks for your reply! Idon't mean Player should play the RTP samples at NTP time. I know that using RTCP SR, (Audio sample)timestamp->NTP, and (Video sample)timestamp->NTP. So Audio and Video can synchronize on a timebase. Is this right? how does Player(VLC) create a timebase? Is there any relation...

I analysized Audio/Video synchronization (Raw/RTP/UDP, not TS/RTP/UDP). and I know, using RTCP SR, Audio timestamp ->NTP,and Video timestamp->NTP。 So Audio and Video can synchronize on a timebase. VLC has its systemclock(gettimeday(), as a timebase?), but when to play using NTP? my understanding is ...

Thanks！

and in which version VLC will implement receiver-side RTCP with the RTP plugin?

I'm reading the /demux/live555.cpp (the verison is vlc-0.8.6h-). I find that it creates subsessions for each media in the SDP, and setup, finally play. so if SDP has one video and two audioes, VLC will receive all. for example, SDP has one video, one French audio, one English auido. VLC will receive...

in mail list, I have found: 1、VLC doesn't support RTCP server-side, and client-side, only with liveMedia. 2、VLC 0.8.6 stream output does not implement RTCP. For broadcast, it's been added in version 0.9.0. 3、VLC does only RTCP reception on the client side, with the use of Live555 library. 4、RTCP cli...

Thanks!

so when I read the source code (the newest version), the Hack's guide isn't useful.

Is there another other useful document?

hi, all! I'm reading the VLC's Hacker's guide, and find this sentence: the main thread becomes the interface thread. It passes through the following steps: 1.CPU detection * 8.Audio output thread spawning ; 9.Video output thread spawning ; but when I'm reading the VLC's source code (the version is v...
