  31       <div class="body">
  32         <p>A while back, I was asked by a friend how to stream the desktop to
  33 my projector connected to Kodi.  I sadly had to admit that I had no
  34 idea, as it was a task I never had tried.  Since then, I have been
  35 looking for a way to do so, preferable without much extra software to
  36 install on either side.  Today I found a way that seem to kind of
  37 work.  Not great, but it is a start.</p>
  38
  39 <p>I had a look at several approaches, for example
  40 <a href="https://github.com/mfoetsch/dlna_live_streaming">using uPnP
  41 DLNA as described in 2011</a>, but it required a uPnP server, fuse and
  42 local storage enough to store the stream locally.  This is not going
  43 to work well for me, lacking enough free space, and it would
  44 impossible for my friend to get working.</p>
  45
  46 <p>Next, it occurred to me that perhaps I could use VLC to create a
  47 video stream that Kodi could play.  Preferably using
  48 broadcast/multicast, to avoid having to change any setup on the Kodi
  49 side when starting such stream.  Unfortunately, the only recipe I
  50 could find using multicast used the rtp protocol, and this protocol
  51 seem to not be supported by Kodi.</p>
  52
  53 <p>On the other hand, the rtsp protocol is working!  Unfortunately I
  54 have to specify the IP address of the streaming machine in both the
  55 sending command and the file on the Kodi server.  But it is showing my
  56 desktop, and thus allow us to have a shared look on the big screen at
  57 the programs I work on.</p>
  58
  59 <p>I did not spend much time investigating codeces.  I combined the
  60 rtp and rtsp recipes from
  61 <a href="https://wiki.videolan.org/Documentation:Streaming_HowTo/Command_Line_Examples/">the
  62 VLC Streaming HowTo/Command Line Examples</a>, and was able to get
  63 this working on the desktop/streaming end.</p>
  64
  65 <blockquote><pre>
  66 vlc screen:// --sout \
  67   '#transcode{vcodec=mp4v,acodec=mpga,vb=800,ab=128}:rtp{dst=projector.local,port=1234,sdp=rtsp://192.168.11.4:8080/test.sdp}'
  68 </pre></blockquote>
  69
  70 <p>I ssh-ed into my Kodi box and created a file like this with the
  71 same IP address:</p>
  72
  73 <blockquote><pre>
  74 echo rtsp://192.168.11.4:8080/test.sdp \
  75   > /storage/videos/screenstream.m3u
  76 </pre></blockquote>
  77
  78 <p>Note the 192.168.11.4 IP address is my desktops IP address.  As far
  79 as I can tell the IP must be hardcoded for this to work.  In other
  80 words, if someone elses machine is going to do the steaming, you have
  81 to update screenstream.m4u on the Kodi machine and adjust the vlc
  82 recipe.  To get started, locate the file in Kodi and select the m3u
  83 file while the VLC stream is running.  The desktop then show up in my
  84 big screen. :)</p>
  85
  86 <p>When using the same technique to stream a video file with audio,
  87 the audio quality is really bad.  No idea if the problem is package
  88 loss or bad parameters for the transcode.  I do not know VLC nor Kodi
  89 enough to tell.</p>
  90
  91 <p><strong>Update 2018-07-12</strong>: Johannes Schauer send me a few
  92 succestions and reminded me about an important step.  The "screen:"
  93 input source is only available once the vlc-plugin-access-extra
  94 package is installed on Debian.  Without it, you will see this error
  95 message: "VLC is unable to open the MRL 'screen://'.  Check the log
  96 for details."  He further found that it is possible to drop some parts
  97 of the VLC command line to reduce the amount of hardcoded information.
  98 It is also useful to consider using cvlc to avoid having the VLC
  99 window in the desktop view.  In sum, this give us this command line on
 100 the source end
 101
 102 <blockquote><pre>
 103 cvlc screen:// --sout \
 104   '#transcode{vcodec=mp4v,acodec=mpga,vb=800,ab=128}:rtp{sdp=rtsp://:8080/}'
 105 </pre></blockquote>
 106
 107 <p>and this on the Kodi end<p>
 108
 109 <blockquote><pre>
 110 echo rtsp://192.168.11.4:8080/ \
 111   > /storage/videos/screenstream.m3u
 112 </pre></blockquote>
 113
 114 <p>Still bad image quality, though.  But I did discover that streaming
 115 a DVD using dvdsimple:///dev/dvd as the source had excellent video and
 116 audio quality, so I guess the issue is in the input or transcoding
 117 parts, not the rtsp part.  I've tried to change the vb and ab
 118 parameters to use more bandwidth, but it did not make a
 119 difference.</p>
 120
 121 <p>I further received a suggestion from Einar Haraldseid to try using
 122 gstreamer instead of VLC, and this proved to work great!  He also
 123 provided me with the trick to get Kodi to use a multicast stream as
 124 its source.  By using this monstrous oneliner, I can stream my desktop
 125 with good video quality in reasonable framerate to the 239.255.0.1
 126 multicast address on port 1234:
 127
 128 <blockquote><pre>
 129 gst-launch-1.0 ximagesrc use-damage=0 ! video/x-raw,framerate=30/1 ! \
 130   videoconvert ! queue2 ! \
 131   x264enc bitrate=8000 speed-preset=superfast tune=zerolatency qp-min=30 \
 132   key-int-max=15 bframes=2 ! video/x-h264,profile=high ! queue2 ! \
 133   mpegtsmux alignment=7 name=mux ! rndbuffersize max=1316 min=1316 ! \
 134   udpsink host=239.255.0.1 port=1234 ttl-mc=0 auto-multicast=1 sync=0 \
 135   pulsesrc device=$(pactl list | grep -A2 'Source #' | \
 136     grep 'Name: .*\.monitor$' |  cut -d" " -f2|head -1) ! \
 137   audioconvert ! queue2 ! avenc_aac ! queue2 ! mux.
 138 </pre></blockquote>
 139
 140 <p>and this on the Kodi end<p>
 141
 142 <blockquote><pre>
 143 echo udp://@239.255.0.1:1234 \
 144   > /storage/videos/screenstream.m3u
 145 </pre></blockquote>
 146
 147 <p>Note the trick to pick a valid pulseaudio source.  It might not
 148 pick the one you need.  This approach will of course lead to trouble
 149 if more than one source uses the same multicast port and address.
 150 Note the ttl-mc=0 setting, which limit the multicast packages to the
 151 local network.  If the value is increased, your screen will be
 152 broadcasted further, one network "hop" for each increase (read up on
 153 multicast to learn more. :)!</p>
 154
 155 <p>Having cracked how to get Kodi to receive multicast streams, I
 156 could use this VLC command to stream to the same multicast address.
 157 The image quality is way better than the rtsp approach.</p>
 158
 159 <blockquote><pre>
 160 cvlc screen:// --sout '#transcode{vcodec=mp4v,acodec=mpga,vb=800,ab=128}:rtp{mux=ts,dst=239.255.0.1,port=1234,sdp=sap}'

 187 <a href="http://people.skolelinux.org/pere/blog/What_is_the_most_supported_MIME_type_in_Debian_.html">I
 188 measured what the most supported MIME type in Debian was</a>, by
 189 analysing the desktop files in all packages in the archive.  Since
 190 then, the DEP-11 AppStream system has been put into production, making
 191 the task a lot easier.  This made me want to repeat the measurement,
 192 to see how much things changed.  Here are the new numbers, for
 193 unstable only this time:

 222 <p>The list was created like this using a sid chroot: "cat

 224 - \S+\/\S+$/ {print $2 }' | sort | uniq -c | sort -nr | head -20"</p>
 225
 226 <p>It is interesting to see how image formats have passed text/plain
 227 as the most announced supported MIME type.  These days, thanks to the
 228 AppStream system, if you run into a file format you do not know, and
 229 want to figure out which packages support the format, you can find the
 230 MIME type of the file using "file --mime &lt;filename&gt;", and then
 231 look up all packages announcing support for this format in their
 232 AppStream metadata (XML or .desktop file) using "appstreamcli
 233 what-provides mimetype &lt;mime-type&gt;.  For example if you, like
 234 me, want to know which packages support inode/directory, you can get a
 235 list like this:</p>
 236
 237 <p><blockquote><pre>
 238 % appstreamcli what-provides mimetype inode/directory | grep Package: | sort
 239 Package: anjuta
 240 Package: audacious
 241 Package: baobab

 267 </pre></blockquote></p>
 268
 269 <p>Using the same method, I can quickly discover that the Sketchup file
 270 format is not yet supported by any package in Debian:</p>
 271
 272 <p><blockquote><pre>
 273 % appstreamcli what-provides mimetype  application/vnd.sketchup.skp
 274 Could not find component providing 'mimetype::application/vnd.sketchup.skp'.
 275 %
 276 </pre></blockquote></p>
 277
 278 <p>Yesterday I used it to figure out which packages support the STL 3D
 279 format:</p>
 280
 281 <p><blockquote><pre>
 282 % appstreamcli what-provides mimetype  application/sla|grep Package
 283 Package: cura
 284 Package: meshlab

 312       </div>
 313       <div class="body">
 314         <p>Quite regularly, I let my Debian Sid/Unstable chroot stay untouch
 315 for a while, and when I need to update it there is not enough free
 316 space on the disk for apt to do a normal 'apt upgrade'.  I normally
 317 would resolve the issue by doing 'apt install &lt;somepackages&gt;' to
 318 upgrade only some of the packages in one batch, until the amount of
 319 packages to download fall below the amount of free space available.
 320 Today, I had about 500 packages to upgrade, and after a while I got
 321 tired of trying to install chunks of packages manually.  I concluded
 322 that I did not have the spare hours required to complete the task, and
 323 decided to see if I could automate it.  I came up with this small
 324 script which I call 'apt-in-chunks':</p>
 325
 326 <p><blockquote><pre>
 327 #!/bin/sh
 328 #
 329 # Upgrade packages when the disk is too full to upgrade every
 330 # upgradable package in one lump.  Fetching packages to upgrade using
 331 # apt, and then installing using dpkg, to avoid changing the package
 332 # flag for manual/automatic.
 333
 334 set -e
 335
 336 ignore() {
 337     if [ "$1" ]; then
 338         grep -v "$1"
 339     else
 340         cat
 341     fi
 342 }
 343
 344 for p in $(apt list --upgradable | ignore "$@" |cut -d/ -f1 | grep -v '^Listing...'); do
 345     echo "Upgrading $p"
 346     apt clean
 347     apt install --download-only -y $p
 348     for f in /var/cache/apt/archives/*.deb; do
 349         if [ -e "$f" ]; then
 350             dpkg -i /var/cache/apt/archives/*.deb
 351             break
 352         fi
 353     done
 354 done
 355 </pre></blockquote></p>
 356
 357 <p>The script will extract the list of packages to upgrade, try to
 358 download the packages needed to upgrade one package, install the
 359 downloaded packages using dpkg.  The idea is to upgrade packages
 360 without changing the APT mark for the package (ie the one recording of
 361 the package was manually requested or pulled in as a dependency).  To
 362 use it, simply run it as root from the command line.  If it fail, try
 363 'apt install -f' to clean up the mess and run the script again.  This
 364 might happen if the new packages conflict with one of the old
 365 packages.  dpkg is unable to remove, while apt can do this.</p>
 366
 367 <p>It take one option, a package to ignore in the list of packages to
 368 upgrade.  The option to ignore a package is there to be able to skip
 369 the packages that are simply too large to unpack.  Today this was
 370 'ghc', but I have run into other large packages causing similar
 371 problems earlier (like TeX).</p>
 372
 373 <p>Update 2018-07-08: Thanks to Paul Wise, I am aware of two
 374 alternative ways to handle this.  The "unattended-upgrades
 375 --minimal-upgrade-steps" option will try to calculate upgrade sets for
 376 each package to upgrade, and then upgrade them in order, smallest set
 377 first.  It might be a better option than my above mentioned script.
 378 Also, "aptutude upgrade" can upgrade single packages, thus avoiding
 379 the need for using "dpkg -i" in the script above.</p>
