H264 : 086h

[trok]

I don't know why but with VLC I cant use VLC as Server to stream video in H264.
Have you found an issue to fixe this problem ? Perhaps 086i... (I dream about that all the time a new release is build)

Use condition:
I use a VLC as server to provide a video stream over my LAN and I use an other VLC as client to read this stream. I use a RTSP connection between the 2 VLC (Server & client).

Next nothing.......

[trok]

I try with last build of this night (090) and unfortunatly it's not better.
I have juste the sound and no image (not a black screen => nothing).

[trok]

90 read => no answer !!
Nobody have a little idea about this old regression ?

[vibes992000]

Please note that when we use VLC to stream H.264 then the client takes 15 seconds extra to start the video. Generally the Voice is preceded before audio for first 15 seconds .. i.e have u waited for at-least 30 seconds on the client side after pressing start button ??

[trok]

Of sure ! So this problem is very old since 086b

[trok]

No issue to fixe this very very old bug ? It will be nice to do something for new version... To my mind it's more important that add a commande line like "hide window" or anything else.
We talk about the motor of your software and not his F*** design.

fyi => 086i always buggy (you have this bug in the 8 older version and not before). Winmerge between 086a and 086b shall help you.

Thanks !

How often do you have keyframes in the video? We put one in every 5 seconds when RTP streaming H.264. You might not get video until you get a "real' frame. Just a thought...

I haven't configured or changed key frames in streaming. Its default values only. I'm using VLM script as given under

Code: Select all

new test broadcast setup test input "dshow://" setup test option dshow-vdev="Osprey-230 Video Device 1" setup test option dshow-adev="Osprey-230 Audio Device 1" setup test option dshow-size="" setup test output #transcode{vcodec=h264,vb=96,scale=0.5,acodec=mp2a,ab=16,channels=1}:duplicate{dst=std{access=http,mux=ts,dst=:80}} setup test enabled control test play

[Heion]

I have trouble streaming and transcoding H264 as well, see my post here: viewtopic.php?f=4&t=48480#p154577

[trok]

I think the dev who done this codec has left the VLC team and now nobody can correct bugs in this software part. So it's a new bug between 086a and 086b. It's not possible to understand what have change with a file comparator between 086a and 086b (as winmerge, kdiff, beyound compare) ?

[Heion]

If that's true, then I hope VLC as a whole can prioritize this. H264 is a popular and widely used video compression these days, I'm starting to use it myself and need proper support for it in VLC. Of course, VLC plays H264 files, but transcoding/streaming them is not possible at the moment.
