Pipe for injection? #55

Closed Manouchehri closed 1 year ago

Manouchehri commented 1 year ago

Would it be possible to add support to accept a pipe for the hevc input stream? e.g. like this:

ffmpeg -i Untitledforhdr10injection265.mov -map 0:v:0 -c copy -vbsf hevc_mp4toannexb -f hevc - | hdr10plus_tool inject -i - -j metadata.json -o /tmp/injected_output.hevc

This errors out with:

No it's not supported, we rely on being able to figure out the proper frame presentation order, which requires parsing the whole video first. When parsing, the frames can come in any order and buffering a full GOP isn't an option.
