Description

When I tanscode the video from webm to mp4 with javacv. A warning appeared:bitrate can't be controlled for RC_QUALITY_MODE,RC_BITRATE_MODE and RC_TIMESTAMP_MODE without enabling skpi frame. In addition, the bitrate of the video is lower than the original video.

Contributor guide

Research direction
Inspect the warning 'bitrate can't be controlled for RC QUALITY MODE,RC BITRATE MODE and RC TIMESTAMP MODE without enabling skip frame' and trace the FFmpeg option handling in JavaCV's FFmpegFrameRecorder to understand how bitrate settings are passed.
