x264 must be compiled with --bit-depth=10. Note that the resulting build will not be able to output 8-bit depth. Of course you can have separate builds, but whatever build ffmpeg is linked to will determine what bit depth it can output.

You could possibly use the curves filter. It has a lighter preset: ffmpeg -i input -vf curves=preset=lighter -c:a copy output The red, green, and blue components can be adjusted separately. The following is the same as what the lighter preset uses: curves=r='0.4/0.5':g='0.4/0.5':b='0.4/0.5' Additionally you can make your own curves preset in ...

Same frame rate for input and output If you want to input and output to have the same frame rate, then just provide the input frame rate. This example will set a ...

The best and recommended way around this, is to generate alternate streams for the video before trying to play it. ...

I have seen this also with libfdk_aac and x264 and am not sure what causes it but I have had success using the itsoffset flag like this: ffmpeg -itsoffset 0.046440 -i original.wav -c:a libfdk_aac -vbr 5 ffmpeg.m4a
