h264 modify 800x448 to 448x800 #34

Closed yinjun622 closed 4 years ago

yinjun622 commented 5 years ago

When playing h264 video, modify 800x448 to 448x800, it can't display normally.

ffplay plays normally. d.h264.zip

I just tested. It played fine. What issue you have having?

I just saw some distortion frames in between

but my question is that when the width and height are changed, it can't be shown like ffplay.

Sorry I was extremely busy for the last few weeks. I got your point. Basically I do not re-fetch PPS and SPS once it I got it unless you reset it manually. Please check this to get an idea. Basically you can adjust code there if you want to fetch PPS and SPS every time and of-course it is performance issue

==> How to make re-fetch PPS and SPS based on the size change dynamically?
