`ffmpeg -f v4l2 -r 30 -s hd720 -c:v mjpeg -i /dev/video0 -c:v h264 output.mp4`
When recording, ffmpeg litters stderr with the error: "unable to decode APP
fields: Invalid data found when processing input". This is from the mjpeg
module.
VLC (and mpv, among others) will play the resulting video without any
complaints, due to the `-c:v h264` option invoking the x264 encoder, although it
is played at about 4x its original speed for some reason. The integrated Firefox
player now refuses to play the file entirely: "Video can't be played because the
file is corrupt.".

A big tracker is the application I'm most familiar with that handles this kind of stuff, but it seems a lot to install for a single person - I guess a complete SQL database and web-server would be amongst the dependencies. I'd appreciate any thoughts, Stroller. Hi Stroller, As a nautical type, much would depend on the size of the boat. But there are tricks:: 1. Keep a multi-sheet notepad with the boat, so you can scribble down notes, ideas and todo items. Later, you can take that tablet, type it up and keep a copy with the boat, for further/deeper annotation. 2. Never smoke in, near or around the boat, unless it is diesel. A few signs to such is always a good idea. Smoking back at the keyboard, is usually OK. 3. USE the dam thing, so you can remember why you started pumping lots of cash into it. Mine, I have keg parties, with the keg & ice inside the boat, so the boat receives lots of love from you friends. Quite often, this is the best use of a boat, regardless if trailered or tied up to a doc or wherever. 4. Dual batteries are a necessity: one of cranking and one to run the supervisory electronics that ensures the perfect (or close to it) temperature for the beer 5. Almost forgot, if you do intend to actually use the boat, insurance is a must, both for sinking and liabilities... 6. GNUcash is a great app for all things financial, particulary if you use the boat for business and want to track expenses and make your accountant happy. Big boats are easy to include with a C or S corp and save you big in expenses hth, James

[gentoo-user] FFmpeg and AVI1'd M-JPEGs
Hi List,
A while ago, I made the grave mistake of buying a Logitech C270 webcam [1],
which initially seemed to be well-supported under Linux as a U.V.C.\ camera [2].
As shown by the following (partial) output of `v4l2-ctl --list-formats-ext`
suggests, the full 720p@30fps is only supported when using MJPG.
ioctl: VIDIOC_ENUM_FMT
Type: Video Capture
[0]: 'YUYV' (YUYV 4:2:2)
[...]
Size: Discrete 1280x720
Interval: Discrete 0.133s (7.500 fps)
Interval: Discrete 0.200s (5.000 fps)
[...]
[1]: 'MJPG' (Motion-JPEG, compressed)
Size: Discrete 1280x720
Interval: Discrete 0.033s (30.000 fps)
Interval: Discrete 0.040s (25.000 fps)
Interval: Discrete 0.050s (20.000 fps)
Interval: Discrete 0.067s (15.000 fps)
Interval: Discrete 0.100s (10.000 fps)
Interval: Discrete 0.200s (5.000 fps)
[...]
Unfortunately, as per [3], Logitech C-series cameras (among others) utilise a
proprietary extension to the Motion-JPEG format, in which H.264 data is attached
to the various JPEG key and delta frames in the APP0 field [4], as shown when
inspecting the data of any frame ("AVI1" [5]):
$ ffmpeg -i video.mp4 -vcodec copy %02d.jpg
$ xxd 01.jpg | head -n 1
: ffd8 ffe0 0021 4156 4931 0001 0101 0078 .!AVI1.x
^^
Thus, FFmpeg (and programs using FFmpeg) seem to have trouble trouble correctly
parsing these MJPG videos, and VLC almost crashes when trying to play one
(although the Firefox integrated mp4 player does fine):
$ vlc output.mp4
[7f2eec008aa0] main video output error: video output creation failed
[7f2ee8c0ae50] main decoder error: failed to create video output
$ ffmpeg -i output.mp4 somethingelse.avi
[mjpeg @ 0x5611aeee7000] unable to decode APP fields: Invalid data found
when processing input
Some work was done on libav many years ago, in an effort to provide a bitstream
filter to ffmpeg to properly convert these to JPEG/JFIF images, however I doubt
it's relevant any more [6], especially considering that Gentoo has removed
libav, and the corresponding USE-flag in `virtual/ffmpeg` is forever-masked [7].
To conclude, is there any method of making these Logitech'd MJPG files play
nicely with FFmpeg (and VLC) ? Someone on the aforementioned Stack Overflow
question pointed out that Skype is able to read both the outer MJPG and inner
H.264 streams, however I cannot confirm this myself. So far, Firefox is the only
program which can play these video files, and I do not want to use that as my
primary video-player !
I also need to provide these files to some non-technical (Windows) users at a
local College, so I want to make them as portable and standards-conformant as
possible.
Thanks for any guidance,
Ashley.
P.S. Other than this, it's an extremely good camera for someone on a budget.

If you don't specify one of those restrictions in one of those places, your mail server is an open relay. Postfix doesn't let you do that. One of them is set by default; smtpd_relay_restrictions end with defer_unauth_destination on new installs.

Re: [gentoo-user] To do list or bug tracker? Project management?
Hello, I can recommend Kanboard (https://kanboard.org/). I use it for my personal IT projects. It implements kanban way of working and is highly customizable. To track dependencies you can use 'Links' (probably a lot of task management application have this feature) and create your own types of connection. You can create columns, swimlanes, categories, tags and so on. There is a lot of plugins which add more functions and integrations with other services. But you need to manually install it (no cloud service), so you need your own hosting (or local server).

They're tiny, and the package is often unusable without them. These are build-only dependencies so "emerge --depclean" can remove them after you install bind-tools. In a source-based distro, you should probably just get comfortable with having a million build tools installed though.

Perhaps a solution from upstream would be to distribute a simplified groff man page with the program, and then the package managers could enable the documentation requiring Sphinx only when the `doc` flag is set. It seems like pre-9.16 versions distributed a lot of basic man pages for all the various tools [1].

[gentoo-user] To do list or bug tracker? Project management?
Hello, Does anyone have any recommendations for a task management app, please? I bought a boat a year ago, and can't keep a track of all the work that needs doing and the things that need fixing. I took a look at To Do apps for my Mac a while back but they all seemed to focus more on the formatting of the list (what font to use and what kind of bullet points), rather than the actual tasks. I'd like something that tracks dependencies - that I need to order this part before I can complete that task, to divide jobs that can be completed now from those that need something else doing first. A big tracker is the application I'm most familiar with that handles this kind of stuff, but it seems a lot to install for a single person - I guess a complete SQL database and web-server would be amongst the dependencies. I'd appreciate any thoughts, Stroller.

The problem is that the man pages are not included in the upstream package, only the source for them.

That's what I want to use, except for fetchmail instead of getmail. I'm taking the suggestions in this thread (thanks), and following the simple mail server guide [1]. I've made precisely two changes in main.cf: soft_bounce = yes, mynetworks_style = host. Everything else is left at its default. Postfix starts okay, but when I 'telnet localhost 25' I get this in the log: fatal: in parameter smtpd_relay_restrictions or smtpd_recipient_restrictions, specify at least one working instance of: reject_unauth_destination, defer_unauth_destination, reject, defer, defer_if_permit or check_relay_domains Which of those restrictions do I specify, and where, and why aren't they set by default? > I also use procmail for filtering - although if you already have this set > up in KMail, that should suffice - and dspam for spam filtering. Yes, KMail is fine for this, with spamassassin. 1. https://wiki.gentoo.org/wiki/Postfix -- Regards, Peter.

Sphinx is required (BDEPEND [1]) to build the man page, as commented in the
ebuild [2]:
# sphinx required for man-page and html creation
BDEPEND="${PYTHON_DEPS}
dev-python/sphinx
virtual/pkgconfig"
> Does bind-tools really need packages like sphinxcontrib-qthelp,

All of these are unfortunate consequences of Sphinx's hefty dependency list [3].
It seems that as the manual pages are installed with the package (regardless of
the `doc` USE-flag), there is no way of mitigating this dependency bloat with
the bind-tools 9.16 series. Hopefully this can be addressed by the developers in
future.

[gentoo-user] dns/bind-tools 9.14 -> 9.16 pulling in 17 new dependencies?!
During my regular update, I see that net-dns/bind-tools is upgrading from 9.14 to 9.16, and that's triggering the installation of _17_ new packages (all apparently related to sphinx and Babel). Is this sort of dependency bloat really necessary? The "doc" flag for bind-tools is not set, so why does it demand that sphinx be installed? Does bind-tools really need packages like sphinxcontrib-qthelp, sphinxcontrib-applehelp, sphinxcontrib-jsmath, sphinxcontrib-htmlhelp? -- Grant
