joost - 2012-02-21

Hi Hieroun,

Thanks for the explanation. I understand the issue now, you cannot read or modify the protocol info from script. It would be nice if it could though..

The Bravia accepts any input, I bet it does not even look at the protocol info. When i use the wrong mux or codec, it just displays garbage.

I noticed the same thing with the duration issue. I was passing the duration info from the file directly to mencoder, while substituting the file for a stream. Then I was surprised it suddenly stopped playing ;)

Now I dont pass duration info to mencoder for streams and when the Bravia reaches the end of the imaginary file it keeps playing, but I guess that may not be the same for all players.

Hello joost69,

Yes. It is OK for transcodder not to specify duration. However, you can see "duration="x:xx:xx.xxx" before protocolInfo= with -d option. I am not sure whether most clients use it or not.

Anyway, I think your script works fine for a lot of clients.

Thanks,
Hiero

Hi there.

I think i asked minidlna to use ffmpeg as transcoder/demuxer, but in debug log i still see it have been changed to mencoder with some kind of default settings.

minidlna.conf:
...
transcode_video_transcoder=ffmpeg
transcode_video_options="-ss $STARTPOSITION -i $SOURCE -vcodec copy"
transcode_video_options="-acodec copy -ab 640 -ar 48000 -ac 6 -vbsf h264_mp4toannexb -f mpegts"
transcode_video_options="-v 0 -loglevel quiet pipe:1"
...

debug output:
...

Panasonic Viere TV start playing after while, but with manu pauses :(
Using minidlna CVS + transcoding patch against 1.0.24.

Any ideas why its acting like that?

Hello normaal,

It seems you are using 50Hz(PAL) based TV.

specify following option.
transcode_video_transcoder_pal=ffmpeg

Hi Hieroun.

Switching to 'transcode_video_transcoder_pal' really switched to ffmpeg as transcoder. But its probably still ignoring my remuxing options (minidlna.conf is in earlier post):

Hello normaal,

Sorry, I made mistake in sample "minidlna.conf".

Replace "transcode_video_options" with "transcode_video_options_pal" as following.

----
transcode_video_transcoder_pal=ffmpeg
transcode_video_options_pal="-ss $STARTPOSITION -i $SOURCE -vcodec copy"
transcode_video_options_pal="-acodec copy -ab 640 -ar 48000 -ac 6 -vbsf h264_mp4toannexb -f mpegts"
transcode_video_options_pal="-v 0 -loglevel quiet pipe:1"

I need to correct sample "minidlna.conf".

Hi again.

I have tried to use your transcoding patch a few times allready, but unfortunately without big success. Default settings for ffmpeg is like slideshow on my low profile dlna server
(not enoght CPU power for full transcode), my custom options (only remux to new container) doesn not start streaming pipe in some reason.

As someone once before, i recomend a bit different concept for transcode.
1) separete hardcoded transcoding from mainstream code. Put all transcoding options and logic to bash scripts to get full dynamic usage. In mainstream code keep only minimum logic
for calling out transcoder(s) for some filetypes and/or some clients and handling transcoder output (pipe) as input for minidlna streamingg capabilities.
Then more people can provide profiles and options to get needed configurations to work. I have some scripts from MediaTomb and they are working on my Panasonic Viera.

# minidlna.conf transcode profiles lines. or section by client
# n=5 fields: extensions array, somekindof client_pattern from request script, SOURCE file, additional options to use directly in ffmpeg or mencoder or analysed by script.

transcoder=[mkv][PANASONIC_tv xx yy zz][/root/bin/transcoder-common.sh][$SOURCE][-]
transcoder=[mp3,LPCM][ipad][ffmpeg][$SOURCE][-v 0 -acodec pcm_s16be -f s16be -ar 4410]
transcoder=[mov][*][/root/bin/transcoder-mov.sh][$SOURCE][-]
transcoder=[mp4][PANASONIC_tv][ffmpeg][$SOURCE][-ss $STARTPOSITION -t $DURATION -i $SOURCE -v 0 -loglevel quiet -async 2 -target pal-dvd pipe:1]
transcoder=[mov][*][/usr/bin/mencoder][$SOURCE][x x x]

What doesn't go under any transcoding profile line (extension/client pairs) these will be streamed directly by minidlna with or without success depending from client potential.

Hello gorata,

No error is found in your log.

The line numbers in scanner.c look different from 1.0.24.
Have you patched against 1.0.24 source?

Hi there.

Still wrestling with 1.0.24-4 patch on ARM :)

1) When using ffmpeg and option directly on minidlna.conf:
transcode_video_transcoder_pal=ffmpeg
transcode_video_options_pal=$SOURCE $STARTPOSITION $DURATION
it result ffmpeg to run shortly and cancelation with message:
File '/media/maa/Movies/mkv_aac_ac3/Cube (1997)/Cube (1997).mkv' already exists. Overwrite ? [y/N] [2012/03/27 20:52:51] upnphttp.c:1681: debug: poll error : No data in Pipe

[2012/03/27 20:52:51] upnphttp.c:1730: info: total bytes : read=0, send=0

2)When using a bit more advanced options:
transcode_video_transcoder_pal=ffmpeg
transcode_video_options_pal='-ss $STARTPOSITION -t $DURATION-i $SOURCE -vcodec copy'
transcode_video_options_pal='-acodec copy -ab 640 -ar 48000 -ac 6 -vbsf h264_mp4toannexb -f mpegts'
transcode_video_options_pal='-v 0 -loglevel quiet pipe:1'
it result cancelation with:
[2012/03/27 21:02:03] upnphttp.c:1581: info: exec ffmpeg as following:

[2012/03/27 21:02:03] upnphttp.c:1730: info: total bytes : read=0, send=0

3) when same option is given without ' or ":
transcode_video_transcoder_pal=ffmpeg
transcode_video_options_pal=-ss $STARTPOSITION -t $DURATION-i $SOURCE -vcodec copy
transcode_video_options_pal=-acodec copy -ab 640 -ar 48000 -ac 6 -vbsf h264_mp4toannexb -f mpegts
transcode_video_options_pal=-v 0 -loglevel quiet pipe:1
it result offcource syntax error right away when starting minidlna
/etc/minidlna.conf: line 78: -t: command not found
/etc/minidlna.conf: line 79: copy: command not found
/etc/minidlna.conf: line 80: 0: command not found

4) calling transcoding script:
transcode_video_transcoder_pal=/srv/minidlna/transcode-common.sh
transcode_video_options_pal=$SOURCE $STARTPOSITION $DURATION
which then calls out command:
ffmpeg -threads 2 -i "${INPUT}" -vcodec copy -acodec copy -vbsf h264_mp4toannexb -f mpegts -y pipe:1

it gives like streaming in logs, but no picture on tv ("pleas wait"... "cannot read file"). The number on last line starts
increasing/changing btw.

What i am doning wrong as anyone else gets transcodings and i get nothing lol.

If same transcoder is called from Mediatomb then is executed command:
ffmpeg -threads 2 -i /media/maa/Movies/mkv_aac_ac3/Cube (1997)/Cube (1997).mkv -vcodec copy -acodec copy -map 0:0 -map 0:1 -vbsf h264_mp4toannexb -f mpegts -y /tmp/mt_transcode_IJV2BW 2>/dev/null
and movie starts at TV.

WidiGMX - 2012-03-31

Hello hieroun,

I am wrestling with 1.0.24-4 patch too.
When I try a to transcode a FLAC file to MP3, the ffmpeg is started three times and killed immediatly. I believe that the HTTP connections were closed in the meantime.

My environment:
* media server:
- minidlna-1.0.24 with minidlna_transcode1.0.24-4
- on Debian squeezeplug Linux 2.6.38-8
- running on a Seagate GoFlex Net, arch=ARMv5TE

* media client:
- Windows Media Player 12.0.7601.17514
- on Windows 7 Home Premium SP1

The minidlna.log is shown below. Please contact me, if you need further informations.

Hello Hiero.

Generally i am using same options for mediatomb: same script is called with only diffrenet output settings. I think the problem is with the pipe:1, mimetype presented by minidlna main code, or something with buffering?
But to be precise I checked again started with Mediatomb:

1)
Transcoding script called at Sat Mar 31 13:01:13 EEST 2012. Mediaplayer is mediatomb.
0 video h264
1 audio ac3
TEXT/UTF not found
-map 0:0 -map 0:1
executing final command:.
ffmpeg -threads 2 -i "/media/maa/Movies/mkv_aac_ac3/Cube (1997)/Cube (1997).mkv" -vcodec copy -acodec copy -map 0:0 -map 0:1 -vbsf h264_mp4toannexb -f mpegts -y /tmp/mt_transcode_GYPRBW 2>/dev/null.

That causes a maybe 10s buffering, and move starts ( Cube (1997).mkv ).

2)
minidlna.conf
transcode_video_transcoder_pal=ffmpeg
transcode_video_options_pal=-ss $STARTPOSITION -t $DURATION -i $SOURCE -vcodec copy -acodec copy -map 0:0 -map 0:1 -vbsf h264_mp4toannexb -f mpegts pipe:1

Hello Hiero,

your fix for Windows Media Player 12 is installed and is working!
But now I recognized that encoding to MP3 is somewhat too heavy for my small ARM system. Therefore I changed to LPCM and all works fine (CPU load: approx. 10%)

Thank you for your famous work!

I made tcpdump from what mediatomb and minidlna offers from same directory.
I can see some differentsis. Is it possible to make minidlna options to disable PAL and NTSC res, and offer additional, mediatomb like res?
Right now my Panasonic TV trys to call PAL section and my custom transcoder (i know that from logs), but it fails (bechause of resolution or FLNA_ORG_FLAGS or file extension or ... )
