Thanks for the answer Yes it is a container, but I guess one can write a DirectShow filter to support containers and codecs (similar to oggdsf for DirectShow players such as WMP and VLC although VLC supports ogg without DirectShow as well). Please correct me if I am wrong, an out of tree module requ...

Hi, Please let me know if this is the right place to ask this, or I should ask in the ML. I want to add support for a new media file format (Audio+Video). It is open-source, I have not decided the license but it does not matter. I can write one DirectShow filter for Windows and one V4L for Linux (an...

thanks, is there anyway I can try 1.2 on Windows? While I have you attention: by sending elapsed time in RTCP SR (using QueryPerformanceCounter instead of gettimeofday) I get fewer PTS is out of range (-X), dropping buffer messages but after some time the time-lag piles up and it is no longer low la...

Interesting, to my surprise I changed file caching (access module) and now stream buffering is down to 20ms! Had changed RTP before but it was not affecting 320ms.
On the other hand PTS delay is not affected, maybe because of the decoder buffering.

Does this bug ticket 3794 mean there is no way to go under 320ms when reading SDP from the filesystem?
I have RTP/UDP multicast so it is rtp caching in my case.

To answer some of my questions here :) and hopefully get an answer for one remaining question 1- It seems resampling could not recover from the clock drift. I figured out that relying on "HARDWARE\\DESCRIPTION\\System\\CentralProcessor\\0" for CPU speed was not a good idea, I changed it to...

Hi, Is there any information on what is the best audio codec for low-latency audio over network? suppose everything is just localhost I tried L16 (both as RFC 2586 and RFC 3190), but the problem with fixed sample-rate seems to be that no matter how much I try the presentation time (PTS) seems to be ...

Hi Remi, Thanks for the information! I actually found the problem was that my packets were corrupted, when fixed VLC was able to play them fine! However I will add RTCP, because not every media player is as robust as VLC is, plus it might be useful even in my scenario: I have now two more questions,...

Hi and happy holidays, I have two question: I have a server that broadcasts RTP over UDP on the localhost (without any RTCP packets) It is only Audio so no need for synchronization really, here is the SDP file I use: v=0 o= - 1 1 IN IP4 127.0.0.1 s=Audio i=Sample Audio t=0 0 a=recvonly a=ptime:20 a=...

Here (http://dl.dropbox.com/u/774657/demo.mpg) is the video file, try opening it in VLC and the file is deleted!

I can confirm this with vlc 1.0.5 release version for Windows on XP I was transcoding h264 to mp2v. C:\Demo>vlc --vout-filter=transform --transform-type=hflip c:\h264.avi --sout=#transcode{vcodec=mp2v,vb=2048,acodec=mp2a,ab=192,scale=1,channels=2,deinterlace,audio-sync}:duplicate{dst=std{access=file...

Ok here it is:

Thanks for support, open community rocks

I have made an AVI video in 8-bit grayscale mode using vfw commands. The bitmap header specifies an 8-bit grayscale video (no compression DIB) of size 640*480 with palette and every thing. I can see the generated video is playing fine using MS media player, but vlc shows green background !!! I am a ...
