This is the non-trimmed m3u8 link. These are done on the hour, so the program starts about 20 minutes in;
Code:
ffmpeg -i "http://cspan-146.c-spanarchives.org:1935/vod/_definst_/mp4:full/2014/03/15/20140315125918001_hd.mp4/playlist.m3u8" -c copy -absf aac_adtstoasc 20140315125918001_hd.mp4
edit:
Here is how they changed the m3u8 link for the trimmed versions as well;
Code:
ffmpeg -i "http://cspan-146.c-spanarchives.org:1935/vod/_definst_/mp4:downloads/318/318331-1/318331-1-MP4-STD/318331-1-MP4-STD_01.mp4/playlist.m3u8" -c copy -absf aac_adtstoasc 318331-1-MP4-STD_01.mp4
