Hello! I have fixed libgav1[1] building on GNU/Hurd Debian. It depends on abseil, which has been fixed in the previous patch[2] of me. So to build libgav1, you need to first build abseil and apt install it.
I have also pushed this patch to upstream at <https://chromium-review.googlesource.com/c/codecs/libgav1/+/6239812>. (The CI there seems to fail with some unknown problem. It needs maintainers of it to check.) After building and installing libgav1, you can test it with its builtin `gav1_decode` tool by following steps. 1. Install ffmpeg. 2. Find one of your favorite video file. Let's say it is `love.mp4`. Other formats supported by ffmpeg are OK. Clip it and convert it to av1 with ffmpeg -i love.mp4 -t 5s -s 960x540 -fpsmax 24 -c:v av1 -c:a none love.vif You may adjust options for the quality and size of the output video as you like. Don't use a too long video. Because it will be decoded into yuv format, which is just a image of every frame. The output file will be super big. 3. Transfer `love.vif` to your GNU/Hurd Debian machine. Decode it with, gav1_decode -v --y4m love.ivf -o love.yuv 4. Transfer `love.yuv` back for testing. Convert it to a another video format you like, ffmpeg -i love.yuv -ss 0 -t 5s love1.mp4 NOTE: You have to manually specify the video time. Otherwise, the video will be a static image, 5. Play the video file and check the content. Thanks for people who helped me.
