Screen recording with ffmpeg?

[Silent-Hunter]

I have installed the ffmpeg in the NAND using "opkg install ffmpeg", but I cannot get the screen to record. Can someone help me?

Here is script:


#!/bin/sh

ffmpeg -video_size 800x480 -framerate 30 -f x11grab -i :0.0 -c:v libx264 -qp 0 -preset ultrafast -profile:v high444 /home/silent/Video/framegrab.hq.mkv
read -p "Press any key to recode. Press Control-C to cancel recoding." -n1 -s
ffmpeg -i /home/silent/Video/framegrab.hq.mkv -c:v libx264 -qp 0 -preset veryslow -profile:v high444 /home/silent/Video/framegrab.hq.recoded.mkv

It tells me video_size is not a valid option. Doing further research, I tried -s instead of -video_size and -r instead of -framerate, but then it tells me -c:v is invalid. Replacing that with -vcodec makes it say that 0 is not a valid option for the parameter qp.

This script works as is on my laptop, why is the ffmpeg on the Pandora so different?

It is old


But there were some pnds around that can do screen recording iirc.


Framerate will not be that great with ffmpeg I'm afraid.

Oh? I haven't seen any. I did get this working by just not specifying a codec, and telling it to write to a .mp4 file, but it has bad compression artifacts. Framerate is good though. But the cursor is messed up.

I did look in the repo, yes. Perhaps it was a recent addition?

uh, no. not recent. 

2013.

how did you look in the repo then ?

I looked in the Multimedia and then the Graphics categories. Then in Utilities. Not knowing a title, I couldn't very well use the search feature. I see that it was in a nonexistant VideoRecorder, Recorder category.

if you had typed "screen recorder" in the search field you would have seen it immediately. On top of that, try google

 

[Silent-Hunter]

Yes, but I didn't know that it would be called that.

FWIW it seems to be under main category 'AudioVideo' not 'VideoRecorder'.  But glad that the boards were able to assist as usual.

I will definately need to update the pnd with a new version of SSR.

Sorry for late reply...but yesterday was without internet.
