[FFmpeg-devel] [PATCH] avformat/hls: look for trailing GET headers with m3u8 extension check

[Leo Izen <leo.izen@gmail.com>]

After commit 6b1f68ccb04d791f0250e05687c346a99ff47ea1 we refuse to use
URLs of the form https://foo.bar/baz.m3u8?foo=bar because it fails the
file extension check. This commit strips the ?foo=bar at the end before
checking the file extension.
