[FFmpeg-devel] Bug report

[Dan Rose]

I tried to submit this on the bug tracker, but it never sent a verification email so posting here.

The `-protocol_whitelist ALL` option appears to be broken. I expect it to allow any protocol as per documentation https://ffmpeg.org/ffmpeg-protocols.html#Protocol-Options
> Set a ","-separated list of allowed protocols. "ALL" matches all protocols.

It seems to not match any protocols at all:

$ ffmpeg -v 9 -loglevel 99 -protocol_whitelist ALL -i file://in.mp4 out.mp4L
