Isn't it only necessary to specify "-rawvideo qcif"? I thought that took care of the width and height. -Corey

Danm, you're right. Hmm.. Well, I think I'll leave it as this since this example can be usefull for "very raw" samples... what do you think? Guillaume -- MPlayer's doc is offline. Find some fresh one here: http://tuxrip.free.fr//MPlayer-DOCS-HTML/en/ http://tuxrip.free.fr//MPlayer-DOCS-HTML/fr/

Actually, I was amazed at the total opposite, I got too much random noise, I was expecting green. JK - Any unused space on your HD should be green, so a lot of green makes perfect sense. - ods15

No, only those parts that have never been used (and I also know a few games that have a stupid file format that contains aroud 50% zeroes). But I'm wondering if this might actually be useful to do a first analysis of unknown file formats. Currently I just scroll through with an hex editor, but that is hardly feasible with a 800 MB or so file. Greetings, Reimar Döffinger

Yeah, but it's the green noise that puzzles me. Solid green isn't that common on my harddrive, but there were several parts of green noise.

If /dev/hda4 actually exists on your system, then the error message is erroneous: it's a permissions issue. Try it as root, or grant your normal user read access to the device. -Corey

Looks like the "File not found" error is printed regardless of the reason open() failed. Look at demuxer.c at about line 120: f=open(filename,m); if(f<0) { mp_msg(MSGT_OPEN,MSGL_ERR,MSGTR_FileNotFound,filename); m_struct_free(&stream_opts,opts); return STREAM_ERROR; } I'll go ahead and make a patch to look at errno and print appropriate messages for any errors that might happen. -Corey

giving user read permissions to hda is the same as giving the user root. read hda = read /etc/shadow = have root after a few hours of running john...
