VOL HEADERS NOT RECEIVED in MPEG4 stream

[tucano]

I'm trying to stream an mpeg4 clip from a server to a client (unicast).

I always get the error "waiting for VOL", so the client wait for this header but it doesn't get it...Infact it gets only the audio stream.

I think I cannot modify the headers, so how can I solve this problem?
I get the same errors transmitting on RTP or HTTP

Here's my tipical output:

I think I have the same problem on my setup, although I found a way to work-around this.

To work this around, you can check the "transcoding" option and use "mp4v" as the codec for video, and try to play the file, then the player/receiver should have no problem to get the "VOL" info.

Then I just stopped this stream and uncheck the transcoding option and the receiver can now render the video clip w/o problems. It seemed to me the problem is on the player/receiver side.

Can anyone on this board kindly suggest how to trully fix this problem?

Thanks.

I didn't understand the procedure...
I tried to check the "transcode" option on the receiver and checked the mp4v video option, but it's the same. It desn't get the VOL...
What do you mean with "stopping the stream" ?


P.S. I was able to stream an MP4 video too, but I had to change the container of the file... I had to convert it with an external software ( IMTOO mpeg encoder ) to the format DivX which has "avi" container( it uses mpeg4 codec for video and mp3 codec for audio )... with this solution I was able to steam and receive an mpeg4, but I'm not sure if the performances of the .avi are the same as the .mp4.
