        ^ $(CC) $(CFLAGS) to be more generic and allow overriding.

The LDFLAGS "$(LAV_FLAGS) -lpthread" need to be at the end of the
command for my compile/link chains to work. *shrug*

Make this "rm -f" to silence warnings about non-existant files.

It may be me, but the whole thing doesn't work for me.

With any MP4 file, I get:

[AVIOContext @ 0xa3c3b40] {
        "free": 16,
        "reserved": 0,
        "wait": 0,
        "writable": 0,
        "busy": 0,
        "buffer_full": 0,
        "current_read": -1,
        "newest_write": 0,
        "oldest_write": -1
}

gdb, if it's of interest:

(ffmpeg of the same version as the libs has no issue processing the
same file to matroska.)

Using an MKV as input, it launches as such:

[AVIOContext @ 0xb441e5c0] {
        "free": 16,
        "reserved": 0,
        "wait": 0,
        "writable": 0,
        "busy": 0,
        "buffer_full": 0,
        "current_read": -1,
        "newest_write": 0,
        "oldest_write": -1
}
[matroska,webm @ 0xa166580] Finding video stream.
[AVIOContext @ 0xb441e5c0] Shutting down http server.

"Shutting down"??? And I can't connect and play.

It may just be me though. Hope this helps anyway.
