Sorry for the late reply. Found this old e-mail while cleaning my inbox.
I haven't uploaded a video to Youtube in years, so you may be right about
Youtube today. I don't know.
What I do know is that 7 years ago Youtube accepted a mkv[h264(gbrp)+wavpack]
file I uploaded and is still up today.
Obviously Youtube converted the completely lossless mkv-file to lossy H.264
video and lossy AAC audio and so, contrary to what OP thinks, doesn't preserve
the original lossless file.
You would have to try if Youtube still accepts such a lossless file. This was
the Avisynth-script I used for it:
~~~~~~
FFAudioSource("input.tak")
AudioTrim(59900148/44100, 0)
AudioTrim((59900148%44100)/44100.0, 0)
Audio=AudioTrim(0, -13374648/44100) + AudioTrim(13374648/44100,
-(13374648%44100)/44100.0)
Video=ImageSource("input.png",end=AudioLength(Audio)*25/AudioRate(Audio),fps=25).Spline36Resize(360,360)
AudioDub(Video,Audio)
~~~~~~
And the FFmpeg-command:
ffmpeg.exe -i "input.avs" -c:v libx264rgb -preset slower -tune stillimage -qp 0
-c:a wavpack -compression_level 4 "output.mkv"
