From b022d9ba288ad3de321e0835b0aedfd91c2c3064 Mon Sep 17 00:00:00 2001 From: Aman Gupta Date: Thu, 29 Aug 2019 16:00:50 -0700 Subject: [PATCH] avcodec/omx: fix xFramerate calculation Integer overflow in the Q16 framerate calculation was sending invalid values to the OMX encoder. On the RPI4, this manifested as bitrate controls being ignored on video streams with 60000/1001 framerates. Video streams with 30000/1001 framerates were not affected.
