Hi,

3.1 is already old version but I’m using 3.0.5 in my project and I updated 
today it to 3.2.2.

avcodec_decode_video2 is deprecated but still works so I tested decoding with 
1920x1080 with 3.2.2.


1. Change just library

Decoding speed of avcodec_decode_vdeo2 for 3.2.2 is slow (0.03 sec / frame ) 
than 3.0.5 (0.001 or less / frame) so 1920x1080 video for 3.2.2 stopped 
frequently but not for 3.0.5.

2. Fix deprecated functions

The result is same. After changing avcodec_decode_video2 to avcodec_send_packet 
and avcodec_receive_frame, 3.2.2 still slow decoding speed.


Any idea for this?

Thanks.
