2 hour .flv file, sound not working

[Xirix]

Not sure if anyone here will be able to help with this, but I thought I'd ask.

I have two .flv files that are about 2 hours long each, but both download with no audio for some reason. I've tried VLC, MPC with CCCP codecs, a couple .flv specific players, nothing. I'm unsure of what's going on.

The two videos in question are the two Pathfinder parts in this url.

If you watch the video on blip, it's fine, downloading it with the filelink in the RSS, or with a video downloader, no audio.

Players might not like the speex audio. You could extract the raw streams using FLV Extract, convert the audio to something usable using ffmpeg and then mux to e.g. mkv or mp4.

Converting results in somehow b0rked files, but if all you want to do is to play them using e.g. MPC try the following:
ffmpeg -v quiet -i "Counter Monkey - Pathfinder Live! (Session 1, Part 1).flv" -vcodec copy -acodec libvorbis output_part1.mkv

/edit:
seemingly non-b0rked files:
1. extract using FLV Extract
2. ffmpeg -v quiet -i "Counter Monkey - Pathfinder Live! (Session 1, Part 1).flv" -vn part1.aac
3. muxer -i "Counter Monkey - Pathfinder Live! (Session 1, Part 1).h264"?fps=25 -i part1.aac?language=eng -o part1.mp4

"muxer.exe" is from L-Smash standalone (http://www.mediafire.com/?9l2u6z4s3i9zu).

LAV (http://forum.doom9.org/showpost.php?p=1573510&postcount=10854) now supports speex.
