Get dimensions (pixels location) of the window that you want to capture, for screen-casting remote desktop , screen recording Desktop capture screen-capture with:
sleep 5 && ffmpeg -f alsa -ac 1 -i pulse -f x11grab -r 10 -s 1024x720 -i :0.0 -acodec pcm_s16le -vcodec libx264 -preset ultrafast -crf 0 -threads 0 output-file1.mkv
- TIP: Disable your screen saver. That -will- interfere with the video that is captured. This is not semantic, instead it captures pixels (raster).
Download ffmpeg for Windows (daily/nightly build): http://FFmpeg.Zeranoe.com/builds/win32/static/ffmpeg-latest-win32-static.7z
When using mkisofs don't forget to include "
ERRCTL="WARN|ALL *" in the command line. Otherwise, if mkiso encounters a warning and certainly any errors, it will stop abort. uugh. Overcome that default beahvior by including that.
- RIP 13.7 has all of the optical disc open-source software listed below, except libcdio ("cd-info", in particular).
libCDio from GNU
offers (at least one) tool that can query (report) stats status state of optical media (CD-Rs, DVD+Rs)
libcdio-utils: sample applications based on the CDIO libraries
This package contains a collection of small libcdio-based tools: * cd-drive show CD-ROM drive characteristics * cd-info show information about a CD or CD-image * cd-paranoia an audio CD ripper * cd-read read information from a CD or CD-image * cdda-player a simple curses-based audio CD player * iso-info show information about an ISO 9660 image * iso-read read portions of an ISO 9660 image * mmc-tool issue low-level commands to a CD drive
which, in turn 
cd-info may need
--dvd switch for DVD R media, of course. (never cd-rs, I assume)
cd-info --dvd --iso9660
isoinfo -d -i /mnt/image/2014may7.iso
- is like cd-info's
--iso9660switch. (well a combination of that and ...)
isoinfo -f -i /mnt/image/2014may7.iso
- to either role/mode/command (report '-d' primary volume Descriptor (info head about volume as a whole) or list (find) "-l" contents (all files and folders)) -- optionally add switches "
-J" for Joliet and
-Rfor RockRidge extensions to / layers of the ISO 9660 volume.
cdrwtool -d -i
-toc switches (and maybe
cdrdao disk-info and
xorriso -indev /dev/sr0 -pvd_info
"pvd" stands for Primary Volume Descriptor, which reports information (metadata) about the ISO 9660 filesystem volume (contents of the data track). (the beginning/top thereof)
xorriso -indev /dev/sr0 -toc
"toc" is Table of Contents, which is overhead for teh disc, as a whole, (equivalent to a partition table) -- point: information (data) about the sessions (and tracks) on the disc.
and it's cdrkit equivalent (sister app): icedax (the incredible digital audio extractor)
Compact Disc Digital Audio -> .wav (PCM windows RIFF? container file)
audio "ripping" or extraction
apparently can give some info about even data CD-Rs (and DVD Rs too?)
-J --info-only switch.
Also try mounting the filesystem storage volume on the disc
mount -t iso9660 -o norock,nojoliet -o noatime,uid=1000,gid=100 /dev/sr0 /mnt/image/
optionally add options like "session" to choose which session (if more than one session(track) is on the disc).
The "nojliet" and "norock" mount optiosn instruct the mount command to NOT mount the RockRidge and Joliet extensions/layers to ISO9660.
ImgBurn has Read and Verify modes. It gives details stats figures
except what Windows Explorer gives (which corresponds to cdrecord -minfo (msinfo mode too?) for "Free:" free/unallocated space (capacity)
see /generate-optical-filesystems (ISO9660 and its optional extensions like Joliet and Rockridge and UDF)
according to the description of the software it may use DVD Info Pro for the stats functionality (aspect).
