#537 Artifact when creating a video from an RZX file

[Alberto Garcia]

This RZX file shows the Spectrum loading a tape for a few seconds, and then a loading error.

If I create an FMF video from this recording and then use ffmpeg to generate a video, in one of the frames the loading screen disappears suddenly for no apparent reason. See the attached screenshot.

fmfconv --raw-sound video.fmf | ffmpeg -i - -i palette.png -filter_complex scale=1280:960:flags=neighbor [x]; [x][1:v] paletteuse -an -c:v zmbv -compression_level:a 12 video.mkv

Reproduced with Fuse 1.10,0, libspectrum 1.7.0 and fuse-utils 1.5.0.

Thanks, should be fixed in [860baa]. The cause was loading the embedded snapshot in the RZX recording not being transparent.

It seems to work fine now, thanks!
