Please provide the command line you tested together with the complete, uncut console output to make this a valid ticket. When you use lossy output codecs (such as MPEG-1 Layer III or AAC), ffmpeg chooses a default bitrate for the output stream, or a variable bitrate. VBR vs. Query syntax: Use tag1 tag2 to match all tags. ; Negate a tag with -tag1. Two-Pass Encoding Please describe your bug. However, the process is complex and slow. . Encoder features such as B-frames, look-ahead, reference B frames, variable bitrate (VBR) As of today, FFmpeg and libav have implemented hardware-accelerated encoding via VAAPI on supported platforms and hardware SKUs, and I have written a write-up on the same that will enable you to set up, deploy ffmpeg -hwaccels | grep vaapi. [h264_vaapi @ 0x55b7251877c0] Driver does not support packed sequence headers, but a global header is request In cases where video quality is the primary concern, it may be better to use a variable bitrate (VBR) encoding method, which adjusts the bitrate based on the complexity of the video content.
