x264 support? #31

Open k0a1a opened 3 years ago

k0a1a commented 3 years ago

Currently mp4 container cannot be opened:

ffmpeg_videoplayer: Supported video codecs:
    decode vp9
    decode vorbis
      codec: libvorbis
    decode opus
      codec: libopus
 No loader found for resource: res://media/echo-hereweare.mp4.
 Cannot load resource from path 'res://media/echo-hereweare.mp4'.

i attempted to add libx264 support in godot-videodecoder/ffmpeg-static/build.sh however to no avail in videodecoder binary.

is there a way of making this work?

thanks!

Afaik h264 is patent encumbered, imo you should reencode in vp8 if you can.

Also getting the compile flags and dependencies working for ffmpeg is a dark art :)

I'm looking to load existing mp4 http streams, which ffmpeg is capable of doing once x264-decoder (and I presume mp4-demuxer) is available. I could transcode x264 -> vp9 on the fly and serve vp9 streams locally but since I need to be able to dynamically switch streams this external chain would complexify my setup too much..
