Hello,
I'm stabilizing a video using OpenCV in the appsink. At the same time I'm saving the file via a filesink.
What I want to do is to reproduce the saved movie with the exact information that I calculated in the first run. To do this I need an exact match between saved frame data and computed stabilization transformations.
Currently, after computing the information I need, I save a txt file with the stabilization transform and sample's buffer PTS.
Although, when reproducing the file, I have an offset between the saved transformation data and PTS and the new reproducing PTS and the offset is not quite constant throughout the whole reproduction.
Currently my pipeline is (simplified) as follows:
(Source connects to both appsink and filesink)
Source --- Appsink
|
-- Filesink
So, I have two main questions:
1) Is the PTS saved in the filesink equal to a PTS (to an offset) of that file's reproduction?
2) How can I synchronize a saved video frame data with a reproduction of the same file?
Thanks,
Diogo
