ctts box

[tokeiro]

Hi everyone.
I´m trying to da an aplication that capture rtp packets enconded in h264 and then construct an .mp4 file.
My problem now its how to generate the ctts box.
Can anyone help me with this?
Best regards

This is rather nontrivial, you'd need to parse sps, pps and slice headers, then compute POC values and assign ctts based on them.
