Set average framerate instead.

3cbe112653 dv: Split DV data table declarations into their own header 
This is necessary to avoid target config settings bleeding into the host
compilation process with hardcoded tables and the DV VLC tables no longer
present as static tables in a header file.

167f3b8de7 libavformat: Add an ff_ prefix to some lavf internal symbols 
Prefix the functions/tables brktimegm, pcm_read_seek,
dv_offset_reset, voc_get_packet, codec_movaudio_tags,
codec_movvideo_tags.

After this, lavf has no global symbols without the proper prefix.

b7effd4e83 avio: avio_ prefixes for get_* functions 
In the name of consistency:
get_byte           -> avio_r8
get_<type>         -> avio_r<type>
get_buffer         -> avio_read

get_partial_buffer will be made private later

get_strz is left out becase I want to change it later to return
something useful.

c6610a216e Prefix all _demuxer, _muxer, _protocol from libavformat and libavdevice. 
This also lists the objects from those two libraries as internal (by adding
the ff_ prefix) so that they can then be hidden via linker scripts.

c76911bd65 Split parts of dvdata.h into dvdata.c, this ensures that things like 
work_chunks_* and dv_idct_factor_* variables appear only once in the binary
instead of 3 times.
Saves 3264 bytes in .rodata and 312416 bytes in .bss on x86_64.

f6765f3f04 Extend DV autodetection to also reliably detect single-frame DVs with 
a higher score that MAX/4.
It checks that there are at least 10 DIF headers and at least one per
24000 bytes, and if so considers the file reliably detected as DV.
Passes probetest, too.

6377de611a Try harder to avoid false positives for DV probe. 
Require at least one signature match per provided 1MB of probe data,
and if there is only a single match, return at most MAX/4.
