OGV/Jukebox test summary: Re: 13.1.0 release candidate 3 (build 22) released

[Mitchell Seaton]

Hi all,

Since reading a recent blog post <http://www.olpcsf.org/node/120> by
Sameer, I was looking into TED video files and OGG (Theora) playback on XO,
I ended up testing with this latest release cand build 22 for 13.1.0 (Sugar
0.98.2).

I have three test machines, XO-1, XO-1.5(HS) and XO 1.75. All have varying
results with playback of Ogg Theora video created with
ffmpeg2theora <http://v2v.cc/~j/ffmpeg2theora/> 0.29 on Fedora 17 (x64_64).
There are mixed results and general bugs with Jukebox (v29) also. I didn't
play around with conversion settings, used the same as in the blog post,
low video compression (lv 6) of sample TED low-quality (320x180) MP4 video
files. Playback tested in Jukebox (v29), Browse (v149) and Totem (Gnome).

Summary, files I created with ffmpeg2theora crash or have stunted playback
on XO 1.75, due to gstreamer 1.0 (F18 arm)?

Note(1), that I tested another Theora file (of Sameer's) created via
gtk-recordmydesktop ((wget
http://verma.sfsu.edu/projects/882-videos/intro.ogv)) and a web downloaded
OGV file ((wget
http://downloads.xiph.org/video/A_Digital_Media_Primer_For_Geeks-360p.webm))
and playback was achievable on XO 1.75, 1.5 and 1.0 without any
errors/crash, except

Note(2), Browse (v149 or v149.4) crashes when trying playback any of the
Ogg Theora video files on 1.75 (as tested).

I can file bugs in SugarLabs <http://bugs.sugarlabs.org/>, have some
activity logs.

Jukebox (v29) issues:
A number of issues reported by humitos here  http://goo.gl/m082T
my observations
- XO 1.5, audio plays, but no video is displayed (blank/black bg)
- Play .OGV files from Journal (Journal/USB drives) and no video display on
startup for all models. Can get video after playing with playlist column.
- http://bugs.sugarlabs.org/ticket/3842 I also confirm, haven't tested some
others.

Currently, Jukebox is not a good user experience for playing video, or a
playlist in Sugar. Other options still exist such as Browse (but fullscreen
button seem's broken on player widget) and Totem in Gnome desktop side.

Also final note(3) is I see a USB auto-mount issue on 1.75 machine, when
I've ejected the USB and reinsert again into a port. Without cmd-line, I
can re-mount by going to Gnome and selecting the drive. Didn't look into
any sys messages for this.

I also tried converting MP4 files to OGV on v27 of ffmpeg2theora on Ubuntu
12.10 x86 sys with same results for outputted OGV file.

Regards,
Mitch
