Append frame

[Igors]

Hi All

My task is to write a QuickTime movie frame by frame from memory (app data).
I tried filesink with "append" property, and, yes, it saves new frames, but
the output movie still has one frame only. Please advice a solution.

Thx

Not sure I understand what you want exactly.

You have frames in memory. Do you want to write them into a single
quicktime file, or do you want one quicktime file for each single
frame?

You probably want something like appsrc ! qtmux ! filesink ?

Cheers

Hi, Tim

Sorry for delay

Frames are written (one by one) into a single .mov file, the problem is:
user can quit from the writer app and restart it, continuing from last ready
frame. How to merge with existing movie ?

Thx
