(edited some useless parts of log out to make it short enough)

I'm having a problem using rtmpdump to download a file. For some reason it seems to keep restarting the download, never completing the entire file. I'm not sure if has something to do with the Pause commands in the log or if the buffer is running out or something else. When I add a -v tag to the command it works, but the file isn't live, so what's up? Please help!

in some cases rtmpdump uses Pause Unpause trick (aka RTMP_LF_BUFX hack) for faster downloading of recorded content. though this works on many servers but few servers send file from beginning instead of respecting the time given in Unpause command. -v | --live switch disables that behavior because this is not applicable to live streams.

alright, so adding the -v to the command is the only way to fix it then?

without code modification it's the only way otherwise simply disable RTMP_LF_BUFX in rtmp.c code and recompile.

greenythebeast · #5 03-04-2012, 08:01 AM

so should i just comment out case 31 in rtmp.c and recompile?

Unless you are only downloading from this site you do not want to change this code. The pause/unpause significantly increases the download speed.

ok. is there anyway to tell RTMPexplorer to use the -v tag when downloading from a certain site?

svnpenn · #8 03-04-2012, 09:01 AM

When RtmpExplorer starts, close the terminal window.

Start a new window with this command.

Code:

rtmpsrv > r.bat

After RtmpExplorer catches the command you can just open the batch file and edit the command.

alright, thanks for the help. any idea how i might be able to automate this on either mac or pc? :P

so im just curious, but what causes it to download so much slower without that hack? using -v works but dear lord is it slow haha. it seems to start fast but then it slows considerably.

anyway, i quickly wrote an application for Mac that automates it. just wish it was faster lol
