Many thanks for the suggestions.
I've tried the method of "ffmpeg". It starts and runs for a short while but then ends prematurely with an error :
Code:
[hls,applehttp @ 02fdd720] Failed to open segment of playlist 0
http://stmw3.rthk.hk/aod/_definst_/radio/archive/radio4/Liveon4/mp3/mp3:20150321.mp3/playlist.m3u8: Unknown error
size= 2500kB time=00:05:20.00 bitrate= 64.0kbits/s
video:0kB audio:2500kB subtitle:0kB other streams:0kB global headers:0kB muxing
overhead: 0.013008%
Is it possible to "resume" the download ?
Also, a couple of lines saying "[mpegts @ 030155c0] PES packet size mismatch" appeared during the execution.
How does this error affect the downloaded file ?
