My Slacko 5.6 derivative didnt like the command:

Code: Select all

# ffmpeg -y -thread_queue_size 384 -f alsa -ac 1 -ar 44100 -i
...
...
Unrecognized option 'thread_queue_size'.
Error splitting the argument list: Option not found

Hello greengeek,

I've uploaded a simple addon for pAVrecord, actually two: one for older ffmpegs, such as may be in Slacko 5.6 and one for newer ffmpegs. All you need to do is to copy the 'hijack' file into /root/.pavrecord (removing the dummy extension as explained in the upload post).

I don't have Slacko 5.6 installed so you would need to try it yourself to see if this addon works on there - all going well the result should be much higher screencast quality (gives same default screencast video quality as SSR quality on my system) if your system and ffmpeg support it.

Please let me know if you try the addon. If it works I'll later put in the first pAVrecord thread post. You can find the addon here:

For more recent ffmpegs, installing new program weX would be a better option - gives same as SSR high quality screencast plus allows user to select capture area or window to capture with the mouse (as well as embedded webcam option).

However, pAVrecord, remains perfectly usable (especially with this addon) - pAVrecord works better with older ffmpegs because it was the first to record the audio and video as separate tracks followed by a merge operation, which addresses some issues of audio/video syncing in older ffmpegs. I was also careful in writing both pAVrecord and weX to make sure that neither of them used any later gtkdialog additions, so work with old gtkdialog3 as supplied in older Pups without any problem.

EDIT: Please post any replies to the relevant pAVrecord thread above.
