There is probably a way to do it directly with ffmpeg on the commandline,
but as I'm not an expert on that, I won't confuse you with guesses.
I have figured out how to generate raw video frames with a C++ program and
have ffmpeg convert it into a video. My ffmpeg command looks like this:
./sh
Ah, thanks a lot for the suggestion, but I should have been clearer that I
need to do this in an automated fashion for arbitrary sets of videos so it
has to be command-line (or a library I guess) so that I can integrate it
into an automated pipeline in my app.
Thanks,
Alex

Hi! I've done something similar to doing this, but I ended up using a
non-linear video editor. Specifically, I used kdenlive. It can do keyframe
animation, so combine that with fade-ins/fade from blacks
I have a question about video compositing. I’ve included the text of the
question below but I’ve also put it in a gist for easier to read formatting
here: https://gist.github.com/alexspeller/aefdd5a6d7100d28d0bbc4838527f797
I have multiple mp4 video files and I want to composite them into a
single
I have a stream of YUV colours (with alpha), stored with raw
`double`s. I want to use ffmpeg -f rawvideo -pix_fmt ayuv64le
to convert this into a normal video format. How should I
encode each pixel so that ffmpeg can decode them?
I would prefer a way to use, for conversion in both directions,

Well, you originally wrote:
