MediaTomb and PS3: The Lazy Man's solution (Part II)

Hi, I'm having some issues with mediatomb and your script. I'm somewhat new to linux, but I've got mediatomb running properly (if I don't try to implement this awesome sounding script) however when I swap in your config.xml file and the mediatomb-transcode.sh I get a vague error in the mediatomb log, and nothing in the mediatomb-transcode log.

Here's the mediatomb log:

2012-02-01 08:55:11 INFO: Loading configuration from: /home/scott/.mediatomb//-p/config.xml

I've checked the permissions on all the related files and made them either 555 or 777
as far as I can tell the mediatomb-transcode.sh isn't getting called (nothing in the log) and I can't figure out why.

I studied programming in college so I'm comfortable with code, but I don't know where to start with this.

Any ideas?

Hi there,

I kept getting Command not found: sel Error.
It took me forever to figure out, that the xmlstarlet command on line 57 has to be adjusted to:


XML=$(which xml)


This is because the FreeBSD Command for XMLStarlet is xml NOT xmlstarlet.

Only works when there are no empty characters. (i.e. 1492.mkv works but The 1492.mvk not)

Second, now there were no thumbnails shown. Without the script they were shown.

Any solutions about that?

Regards

Jose

Has anyone found the solution to the "Permission Denied" on lines 108 and 110 of the mediatomb-multifunctional.sh? I have checked the permissions to the tmp directory and to the mediatomb-multifunctional.sh script and still can't seem to figure this out. Any help would be appreciated

Well it is day three of me working on mediatomb and it appears that your script is just what I wanted - sadly I just can't get it to work. I think I have everything installed for it... When I go to run a MKV it just says data unsupported or data corrupt. The script does create a log file.

I got mediatomb and all the dependencies set up and installed. When I try to play any video from my PS3, I get the following error on the PS3: Media Server Error: A Network Error has Occured (000000000)

In mediatomb, this shows up:

Any thoughts?

I spent a lot of time fixing this script to play most of my movies, music videoclips correctly: read below.
Philips 37PFL9603 DLNA : can only play mpeg2 videos and mp3 music files (and jpg's).
with this tv the video bit rate for HD 1920x1080 mpeg2 needs to be lowered to a certain threshold otherwise the processor of the tv can't decode fast enough. So you can't enjoy every "bit" of your original movie file but sitting from the screen at 2 meters it is not noticeable for me.
I assume newer tv's can decode better codecs (x264 etc) so if I ever earn lots of money I will buy me a new led tv that can play as many codecs possible.

Transcoding HD Movies (720p, 1080p) in real-time results in annoying glitches on the tv that appear every once in a while. Therefore I manually convert them to .mpg files using the mencoder command of mediatomb-multifunctional.sh with specific variables (like "-sid 1" to add the second subtitle from the mkv file or SUBSIZE=40 for HD movies or -subpos 85 etc: see below for details).
The heaviest movie that I converted to .mpg (x264 15 GB .mkv file to 28 GB .mpg file) can play on the tv but sometimes the video stutters or slows down. This quality loss was a bit annoying but I didn't want to spend more time on it trying a lower video bit rate.

Transcoding non-HD movies (mostly xvid) in real-time works: they play instantly on the tv without problem but on a big HD tv screen the image is not so nice. So I prefer HD versions.

A problem with transcoding in real-time is that you can only pause the video. You can't do fast rewind or fast forward. Only if the movie is served as a .mpg file can my tv do fast rewind or fast forward (actually on my tv it is kinda slow so it is only good for rewinding a few seconds or minutes if you have missed parts of a scene)

I first have to set my tv to the PC network, then I have to start the mediatomb program on my computer. Only then does my tv sees the mediatomb directories.
In MediaTomb Web UI I also had to to change the mimetype of some videoclips from "video/x-msvideo" to "video/transcode".

Fix for the function mediainfo:
The Width and Height extracted by the mediainfo program has a space in it when it is over 1000, like "1 200" so I added " | sed 's/ //g'" to the command to remove that space:
VWIDTH=$(${XML} sel -t -m ".//track[@type='Video']" -v "Width" \
${MIOUT} | sed 's/ pixels//' | sed 's/ //g' )
VHEIGHT=$(${XML} sel -t -m ".//track[@type='Video']" -v "Height" \
${MIOUT} | sed 's/ pixels//' | sed 's/ //g' )

vatbier@home videoclips]$ /usr/local/bin/mediatomb-multifunctional.sh Lena_Meyer-Landrut_-_Satellite_Eurovision_Song_Contest_2010_SC_X264_720p.mkv test.mpg
warning: failed to load external entity " "
if you get this warning, then remove the space behind
VWIDTH=$(${XML} sel -t -m ".//track[@type='Video']" -v "Width" \
and behind
VFPS=$(${XML} sel -t -m ".//track[@type='Video']" -v "Frame_rate" \

The fix for subtitles with spaces in their file name:
#OPTS=("")
#OPTS+=(${NOSIZEOPTS})
#echo OPTS: "${OPTS[@]}"
# with command "bash -x ..." you can see that it begins with ''
OPTS=()
# OPTS+=(${M_TR_M} -sub ${SUB} ${SRTOPTS} -o )
# changed to
# OPTS+=(-sub ${SUB} ${M_TR_M} ${SRTOPTS} -o )
# changed to (for subtitles with spaces in filename double quotes are necessary around SUB)
OPTS+=(-sub "${SUB}" ${M_TR_M} ${SRTOPTS} -o )
#exec ${EXEC} "${FILE}" ${OPTS[@]} "${2}" &>/dev/null
# double quotes necessary around OPTS:
exec ${EXEC} "${FILE}" "${OPTS[@]}" "${2}" &>/home/vatbier/.mediatomb/mencoder.log

For the heaviest movie (x264 x264 15 GB .mkv file to 28 GB .mpg file) it was extremely frustrating to find parameters that did not result in buffer underflow with the mencoder command (my tv can't handle buffer underflows in the encoded mpg):
I changed vrc_maxrate to 24000
vrc_buf_size to5350
I added "vbuf_size=400" to -mpegopts
MPEG muxer (-mpegopts)
vbuf_size=<40-1194>
Sets the size of the video decoder's buffer, expressed in kilobytes. Specify it only if the bitrate of the
video stream is too high for the chosen format and if you know perfectly well what you are doing. A too high
value may lead to an unplayable movie, depending on the player's capabilities. When muxing HDTV video a value
of 400 should suffice.
I changed muxrate to 3000000

SUBSIZE=20
# for some hd movies
SUBSIZE=40

# If downscaling is enabled, anything over this width (pixels) will be downscaled.
MAXSIZE=1280

#AABIT=256
# changed to:
AABIT=320

#for 1080p like A.:
#also good for D.
M_TR_M="-sid 1 -slang eng -oac lavc -ovc lavc -of mpeg -lavdopts threads=2 -lavcopts \
abitrate=${AABIT}:vcodec=mpeg2video:keyint=1:vbitrate=20000:\
vrc_maxrate=24000:vrc_buf_size=5350 \
-mpegopts vbuf_size=400:muxrate=3000000 -af lavcresample=44100 "
I put these lines completely to the left (column 0) because otherwise I got a space for the mencoder command: "...vbitrate=20000: vrc_maxrate=24000:..."
# for N. 1080p 10GB
M_TR_M="-sid 0 -slang eng -oac lavc -ovc lavc -of mpeg -lavdopts threads=2 -lavcopts \
abitrate=${AABIT}:vcodec=mpeg2video:keyint=1:vbitrate=20000:\

#added for wmv clips that have wma sound:

vrc_maxrate=${MVBIT}:vrc_buf_size=1835 \
-mpegopts muxrate=100000 -af lavcresample=44100 "

I added "-lavdopts threads=2" in the hope it would process faster.
The "-sid 1" or "-sid 0" depends on the subtitle you want from a .mkv (use mediainfo to see which subtitle you want).

SRTOPTS="-font ${SFONT} -subfont-autoscale 0 \
-subfont-text-scale ${SUBSIZE} -subpos 95 "
# for N.:
SRTOPTS="-font ${SFONT} -subfont-autoscale 0 \
-subfont-text-scale ${SUBSIZE} -subpos 85 "

for each HD movie that is not 16/9 I have to use mediainfo to see what the resolution is and then expand it to 1920x1080 or 1280x720:
#for D.:
SIZEOPTS="-vf harddup,scale=1920:1040,expand=1920:1080 "
#for N. 3 GB:
SIZEOPTS="-vf harddup,scale=1920:796,expand=1920:1080 "

#original:

I have some problems getting this to work. The good news is that videos that previously showed up as unsupported now looks supported on the PS3. But when I try to play them I only get one of these in mediatomb.log

INFO: Arguments %in %out

Nothing is writting in the transcoding log, so it seems the script is not called.

Also, if I try to run the script from the shell I get an error message back:

~$ sudo bash /usr/local/bin/mediatomb-multifunctional.sh
/usr/local/bin/mediatomb-multifunctional.sh: line 120: [: too many arguments

What can be wrong here?

Thanks a lot for this great script!
One thing I'm missing though, moving from PS3Mediaserver, is the ability to pause, FF and REW. This was possible using the PS3Mediaserver (tsMuxer I think). The reason I'd rather go for Mediatomb is option to customize.

Anyonw got a clue how to support pause, ff and rew?

I changed the script slightly to allow for deinterlacing of interlaced content.

I introduced two new variables for the video format:

SIZEOPTS="-vf harddup,scale=720:-2 "
NOSIZEOPTS="-vf harddup "
SIZEOPTS_DE="-vf pp=fd,scale=720:-2 "
NOSIZEOPTS_DE="-vf pp=fd "

and a variable to hold the information from mediainfo:

VFPS=""
VSCAN=""
QPEL=""

It is set in the mediainfo function as follows:

VSCAN=$(${XML} sel -t -m ".//track[@type='Video']" -v "Scan_type" ${MIOUT} )

I then changed the first section in the tropts function:

function tropts {
if [ "${DOWNSCALE}" == "1" -a ${VWIDTH} -gt ${MAXSIZE} ] ; then
if [ "${VSCAN}" == "Interlaced" ] ; then
log "Deinterlacing and rescaling to 720 pixels wide."
OPTS+=(${SIZEOPTS_DE})
else
log "Rescaling to 720 pixels wide."
OPTS+=(${SIZEOPTS})
fi
else
if [ "${VSCAN}" == "Interlaced" ] ; then
log "Deinterlacing and rescaling disabled or file within limits."
OPTS+=(${NOSIZEOPTS_DE})
else
log "Rescaling disabled or file within limits."
OPTS+=(${NOSIZEOPTS})
fi
fi

I am sure it can be done better than using those nested if statements, but I am not much of a shell script programmer. It works though :)

do you have any idea, why audio isn't working in mkv's? im' using lgTV for dlna streaming..

Hi,
I'm having trouble running the script. I am using Ubuntu 10.10. The error appears reports as the following.
