Description
After update FFMPEG to 7.1 version - recording video on Pixel 8 device fails with logs below:
E libdeclarative-camera_arm64-v8a.so: "FFmpeg log: The encoder bitrate is negative." W qt.multimedia.ffmpeg.videoencoder: : Couldn't open video encoder hevc_mediacodec ; result: "Invalid argument" E libdeclarative-camera_arm64-v8a.so: "FFmpeg log: The encoder bitrate is negative." W qt.multimedia.ffmpeg.videoencoder: : Couldn't open video encoder hevc_mediacodec ; result: "Invalid argument" W qt.multimedia.ffmpeg.videoencoder: : No valid video codecs found
Issue can be reproduced with declarative-camera example
It seems that ffmpeg is checking bitrate - that wasn't checked in previous versions
