Hi Everyone,

 

I'd like two questions if possible:

 

1)  How can I convert an RTP Payload H263+ in a MP4 file to H263 ?

 

2)  I'm using mp4play and mp4save with X-Lite. 

 

When I only use X-Lite with h263 codec, it works well. Here the mp4 file
created by X-Lite

 

mp4info save.mp4

mp4info version 1.5.0.1

save.mp4:

Track   Type    Info

1       audio   G.711 uLaw, 10.180 secs, 64 kbps, 8000 Hz

2       hint    Payload PCMU for track 1

3       video   H.263, 6.800 secs, 18 kbps, 176x144 @ 5.882353 fps

4       hint    Payload H263 for track 3 

 

When I only use h263+ codec with X-Lite, I can create the mp4 file but I
can't reproduce it with X-Lite. I can

play it with vlc.

 

mp4info version 1.5.0.1

save.mp4:

Track   Type    Info

1       audio   G.711 uLaw, 12.380 secs, 64 kbps, 8000 Hz

2       hint    Payload PCMU for track 1

3       video   H.263, 9.044 secs, 16 kbps, 176x144 @ 4.975674 fps

4       hint    Payload H263-1998 for track 3

 

Any tip or help ?

 

Thanks in Advanced and a great New Year to everyone 

 

My Best Regards,

 

Andre Lomonaco
