In short: NOPE.avi
In long:
17:12 <@kshishkov> JEEB: found an archive called "LG DVR LEV1 Codec.rar"
17:13 < JEEB> sounds like the same thing
17:14 <@kshishkov> it seems to contain mpeg4 ASP and part 4 decoders ripped from ffmpeg
17:14 < JEEB> LOL
17:15 < JEEB> def. pro corean codecs
17:15 <@kshishkov> ffh264.dll with very familiar strings inside
17:16 <@kshishkov> another one has "This software is derived from the GNU GPL XviD codec (1.1.0).
17:16 <@kshishkov> Your software distributor has to give access to its source code."
17:16 < JEEB> 
17:17 <+nevcairiel> its called ffh264.dll, and you still bother to check strings?
17:17 <+nevcairiel> usually the ff is a dead give away :p
17:17 <@kshishkov> third one has no text except half a dozen functions
17:17 <@kshishkov> like ffmpeg4_get_quants
17:17 <+nevcairiel> odd function name
17:18 <@kshishkov> there's ffmpeg4_decode_frame too
17:19 <@kshishkov> there're audio decoders as well, mentioning some "ADPCM2"
17:20 <@kshishkov> I'd guess IMA ADPCM
In other words, it could be that the thing's already supported if it uses the MPEG-4 and ADPCM stuff from ffmpeg. Try uploading a sample somewhere and linking it here, it'd be nice to test.
