i'm havin trouble with the conversion, every time i try to convert my mp4 file i get a ton of errors in the terminal:

Impossible to convert between the formats supported by the filter 'Parsed_colorspace_1' and the filter 'auto_scale_0'

Conversion failed!

and it generates an empty mp4 file, how do i fix this?

i'm using the following code:

ffmpeg -i input.mp4 -f mp4 -vf "fps=24000/1001, colorspace=space=ycgco:primaries=bt709:trc=bt709:range=pc:iprimaries=bt709:iall=bt709, scale=256:144" -dst_range 1 -color_range 2 -vcodec mpeg4 -profile:v 0 -level 8 -q:v 2 -maxrate 500k -acodec aac -ar 32k -b:a 64000 -ac 1 -slices 1 -g 50 output.mp4

Heya tapping in late, can we get subtitles working as well? Love the project, would love to have my subtitles function in here as well, any way I should modify the syntax? The input file has subtitles tracks.

I can get the subtitles working on FastVideoPlayer DS. But we should make the video hard coded to the subtitles first.
