Dear All, When we play a video at VLC client during the streaming process, is there any way in VLC client to measure the PSNR value (so it will compare reference video and received video)? If it exists, which file (code) I must consider? I only know that PSNR will be calculated during encoding but t...

Dear All, I want to make sure about RTP reordering packet in Audio Video Profile (using H264 packetizer, payload 96, and using SDP file). If at VLC server the sequence number is in order but during transmission, if there is no order packet (e.g server : 1,2,3,4,5 and during transmission the order is...

Thank you for the info.

As fas as I know, for transmitter (VLC server), the sequence number is in modules/stream_out/rtp.c,

Do you know where can I see the sequence number for receiver (VLC client)?

In which part of stats do you mean? in Stats.c?

Thank you for your answers.

Dear All,

Is there any way in VLC to measure how much packet loss happens during video streaming?

I try to check in modules/access/rtp.c (in case of RTP) but I have no idea what parameter to be used for packet loss.

Thank you for the answers.

Thank you so much for your answer. Before I deeply go to the buffer code, I have one more question, Can VLC change playout buffer length automatically during streaming based on the current network condition? e.g : if the network condition is bad, it will add playout buffer length and vice versa. Tha...

Dear All, As far as I know, we can set the playout buffer at the client by using network-caching parameter before streaming. Does it mean that this is the maximum value for playout buffer? Can the playout buffer decrease from the maximum value automatically in VLC? Do you know how to debug (in which...

Thank you,

I am success doing it and it works now.

Dear All VLC forumers, I want to ask a question about streaming video using Audio/Video Profile. On the server, I have already set the parameter as follows : 1. Using RTP Audio/Video Profile 2. Using H264 packetization (rtpmap 96) On the client 1. How to stream this kind of video streaming on the cl...

Thank you so much for your answer.

Is it possible to use rtp:// to get audio and video by using Audio/Video Profile?

If I want to make the client see the video only (without audio), what should I do (in case in AV Profile)? Change the port?

Thank you for the answer

Dear All VLC Forumers, I have a problem streaming a videousing Audio Video Profile. I have succesfully stream the video to the network but when I check the sdp file, it said like this : v=0 o=- 15324391530154056190 15324391530154056190 IN IP4 desktop s=Unnamed i=N/A c=IN IP4 10.0.0.4 t=0 0 a=tool:vl...

Dear all VLC forumers,

As we know well that we usually stream video by using UDP protocol. Is it possible to stream video by using TCP protocol in VLC?
How can I do it (the configuration)?

Thank you so much for the answers.

Dear VLC forumers, I want to stream a video by using transcoding MPEG-2 TS and RTP Audio/Video Profile but when I stream the video, it said that the transcoding is failed, so what is wrong in this case? What transcoding types that are compatible with RTP Audio/Video Profile streaming? Thank you for ...

Hello Edith,

Did you succeed to differentiate each packet with different DSCP value?
As fas as I know, the DSCP value can not be changed for that stream.

Can anyone else know how to differentiate DSCP value in one stream?

Thank you,

I have already taken a look at those files and i have one more question,

Is it possible to make different DSCP value for each packet? so before writing the packet on the network, I want to mark each packet with different DSCP value according to the frame type.

Thank you for the answers

Dear VLC forumers, As far as I know, the DSCP value for differentiate the QoS just can be determined by inputing the value by user. In my case I want to decide the DSCP value inside the source code, for example I want to decide the DSCP value based on the frame type of encoded video. So it will assi...
