ffmpeg - How to specify audio and video bitrate - Super User
https://superuser.com/questions/319542/how-to-specify-audio-and-video-bitrate
In order to specify the target bitrate for video and audio, use the -b:v and -b:a options, respectively. You can use abbreviations like K for kBit/s and M for MBit/s. For example: ffmpeg -i input.mp4 -b:v 1M -b:a 192k output.avi Note: This is a simple one-pass encode that tries to reach the specified bitrate at the end.

ffmpeg -i input -c:v libx264 -b:v 2M -maxrate 2M -bufsize 1M output.mp4. The key option here is -bufsize which tells the encoder how often to calculate the average bit rate and check to see if it conforms to the average bit rate specified on the command line ( -b:v 2M ).

To force the frame rate of the output file to 24 fps: ffmpeg -i input.avi -r 24 output.avi. To force the frame rate of the input file (valid for raw formats only) to 1 fps and the frame rate of the output file to 24 fps: ffmpeg -r 1 -i input.m2v -r 24 output.avi. The format option may be needed for raw input files.

Options may be set by specifying -option value in the FFmpeg tools, or by setting the value explicitly in the AVCodecContext options or using the libavutil/opt.h API for programmatic use. The list of supported options follow: b integer (encoding,audio,video) Set bitrate in bits/s. Default value is 200K. ab integer (encoding,audio)

ffmpeg's -b option refers to bits per second; your game's need to have 16-bit WAV is of a different kind. ffmpeg is right to tell you that 16 bit per second is way too low to get any sort of usable audio from it. Did you listen to the result? Actually, mddnix's answer appears to be the correct one.

ffmpeg -i input_video.mp4 -vf "scale=1200:600" -b:v 10M output_video.mp4 There were two mistakes here:-v:b: the bitrate codec(b) and the stream selector(v for video) were swapped-vf scale: the filter command should be placed between quotes (you can also use the regular scale option instead: -s 1200x600)

Hi guys, I found a new problem using FFmpeg to encode some video / audio streams.My goal was it to encode some diffrent parts of one video out using same audio bitrate but as result I have the parts out with diffrent bitrates what means I can not merge this parts together but for this I need exact same audio bitrate (only for audio needed).Thats a problem …
