rtmpdump - repeats in resulting audio(+)

[zvhotboxru]

First of all i'd like to thanks author for the great program!

My problem is:

rtmpdump -r "rtmp://stream.samurai.fm:1935/vods3" -a "vods3" -f "LNX 11,1,102,55" -W "http://samurai.fm/flash/sfm_soundmanager2c.swf?serverUrl=stream.samurai.fm&pollInterval=250" -p "http://samurai.fm/" -y "mp4:amazons3/origin.samurai.fm/media/d1c632cb/jeff.m4a" -o jeff.flv

its from http://samurai.fm/jeff-b/jeff-b-new-...lk-in-the-park

the resulting audio have repeating parts, like someone pushes rewind for 2-3 secs back (example: http://zv.hotbox.ru/jeff.flv)

output looks like:

Download may be incomplete (downloaded about 1.10%), try resuming

using -v optin sometime helps, but takes too long time (like if you would listen for hole show)

What can I do?

[KSV]

using (-v | --live) switch is your only option to correctly download data from such misbehaving servers. and yeah it will take some extra time to download.

^Hey, look at error, if he input hash and size, it will be dl'ed correctly!!

rtmpdump -r "rtmp://stream.samurai.fm:1935/vods3" -a "vods3" -f "LNX 11,1,102,55" --swfUrl "http://samurai.fm/flash/sfm_soundmanager2c.swf?serverUrl=stream.samurai.fm&pollInterval=250" --swfsize "21808" --swfhash "4acba1208379780d5db7cf30446ab326d80c07b0510c9340b70aacd5ba5677cd" -p "http://samurai.fm/" -y "mp4:amazons3/origin.samurai.fm/media/d1c632cb/jeff.m4a" -o jeff.flv

Also use rtmpdump 2.4!!

(Dunno, maybe in Linux is diff!! )

[KSV]

it has nothing to do with swf verification. it's a known problem with some servers. using -v switch disables RTMP_LF_BUFX hack which causes this weird behavior with some servers.

Thanks so much for explaining!!
