recordMyDesktop, Ogg video files, and OpenShot – part 1

Quick post before bed – I am playing around with using recordMyDesktop on an Ubuntu Linux 11.10 x86 system to create screencasts with, using OpenShot (which looks great by the way) to import and edit video files recordMyDesktop spits out.

To cut a long story short, it seems OpenShot doesn’t like the Theora-encoded video produced by recordMyDesktop:

Ogg video played with ffplay

Numerous postings on the web finger recordMyDesktop as the problematic application – and because recordMyDesktop only outputs Ogg video (which is entirely fair enough), I’m kind of stuck without transcoding it to another format which OpenShot can use without trouble.

In a future post I’ll outline the settings I’m using in VLC Media Player to transcode files created by recordMyDesktop into H264-encoded video in MP4 container format, which can then be imported into OpenShot for editing – and subsequently exported back out as Ogg video (yes, because I actually want my users to be able to view the resulting screencasts in Firefox or Chrome without a bloody plug-in…). Some quality loss is inevitable, so it’s not ideal, but with the right settings it looks like something entirely acceptable is fairly easy to do.

    I have the same problem with videos generated by recordMyDesktop. They are broken with mplayer but they work fine with pitivi. My workaround is to use pitivi to rencode them in avi (xvid), without quality loss.

    Kdenlive also has a fix for ogg from recordmydesktop… uses ffmpeg with the options “-sameq -vcodec libtheora -acodec copy %1.ogv”… encoding is going to take half an hour, I’ll keep you posted… how long did VLC take?
