Re: G711/Buffer Size of 743 Bytes?

On a totally different side note, I've left the streaming open just to test it, it was fine after 1 hour and and then i left the place to get something and when i got back, the video and audio both were gone. The call duration at that time was 1hour 15 minutes. I made a little bit of calculations an...

G711/Buffer Size of 743 Bytes?

Hello forum, I am currently working on a streaming project to an SIP telephony (which uses a non-vlc media engine) and I am trying to send live streams using VLC on the application side. Anyway, I've managed to send audio and video successfully except every now and then (it can happen in 30 seconds ...

Re: Arbitrary Slice Ordering not supported in Baseline Profi

On a second thought, I dont think it should matter whether VLC uses ASO or not while encoding, the SIP telephony should be able to decode it either way.

Hi, I am trying to transcode a live stream's video into h264 format. On the receiver side, I have a SIP telephony that can only handle baseline profiles and sps isnt supported.

For the moment, I am using a .h264 extension file and I can play it on vlc with no problem and the codec setting verifies that its H264-MPEG-4 AVC(part 10)(h264). However, there seems to be a p...

Afterwards, I made some experiments using audio files sampled at different frequencies (8k,11025,22050,44100 etc.). Considering I have only g711(a-law) audio-codec available on the receiver side...

Hello again,

Is there an easy way to change the (rtp)packet sizes inside a transcoded stream or do I need to dig into the packetizer module in vlc?

Thanks.

Re: Rtp/g711 packages

On a side note, for the successfull communications between two IP telephones I am using, there are 160 ms delays between two consecutive audio(g711) packages. I am not sure if this has anything to do with our issue.

Re: Rtp/g711 packages

Does the stream sound correct if you open it in VLC (rtp://@230.0.0.0:8004) ?
yup, it sounds quite alright. The wireshark logs when i listen it on (rtp://@230.0.0.0:8004) look the same (743 ms delays between packages, same Rtp format etc.)

Re: Broadcasting two separate transport streams

yea, I figured. I just couldnt find a way to encode the video input stream(mms/file)to raw h264 by using rtp. The only way i can transport rtp video streams encoded as h264 is when they are encapsulated in mpeg2 streams (which does no good). An rtp stream with no mux type simply displays nothing for...
