TVHeadend Raspberry Pi and Transcoding

Added by lord slash over 3 years ago

Hi guys, I've setup a TVHeadend back end with my raspberry pi and raspbian, where I stream the italian tv to my home in Germany. The system works perfectly during the day, but in the evening the DSL bandwidth is not enough (I need around 4000kbps and I have 3000kbps).

Therefore I would like to try the TVHeadend transcoding option. According to this: https://tvheadend.org/boards/4/topics/13635?r=13637 I should compile after enabling the transcoding in the configuration file src/plumbing/transcoding.c The problem is that in this file there is no uint32_t transcoding_enabled at all. I tried a ./configure --enable-libffmpeg_static and then make and make install, but in the TVHeadend transcoding option is not there :(

What happened to the uint32_t transcoding_enabled ?? How should I compile in order to get transcoding work on my pi? By the way, I have TVHeadend 3.9.1879. Thanks in advance for the help!

Yes! I managed to get gst-launch OMX-transcoding a DVB-C MPEG2-stream to 2 mb/s to a file, I saw it work fully with the RPi1 and RPi3 with MPEG2-license. With the RPi2 I saw it work until the need of a MPEG2-license (which I didn't buy yet for this second hand RPi2), but the main demuxer worked there as well.

I saw synchronous audio and video (I had to absolutely minimize the software-transcoding of audio to get it work)

I needed no compiling, just installing, so no need for the transcoding compiled into TVHeadend and even no difficult selection of an audio stream.

I used berryboot and raspbian Jessie because berryboot makes the image interchangable between RPi1, 2 and 3 and installs the root filesystem on a USB3-stick that makes installing and upgrading twice as fast.

Steps:
Get the actual berryboot image of Raspbian Jessie (I got the initially offered 2016-7-27 version)

sudo apt-get update
sudo apt-get upgrade

(Berryboot doesn't update the boot-kernel during this procedure, but that doesn't matter)

Get all packages for gstreamer (I don't know if this installs unnecessary packages as well)

sudo apt-get install gstreamer1.0
sudo apt-get install gstreamer-1.0

Follow https://tvheadend.org/boards/5/topics/21528 for installing tvheadend. For the RPi1 there is a special dpkg-instruction on page 2, as the right armv6hf-package doesn't come with apt-get:
dpkg -i tvheadend_4.1-2332-g38c9e89_armhf.deb

Make tvheadend tune the channels, or just copy the /home/hts/.hts tree from some working TVHeadend-install.

En then the magic:

gst-launch-1.0 souphttpsrc location="http://127.0.0.1:9981/stream/channel/41ceb7b6ef96f869d7d6c78b6b3a27a6?ticket=24A946694272F14A9994F5F2280E466AB495F745?profile=pass" num-buffers=-1 ! tsdemux name=demux demux. ! queue ! mpegvideoparse ! omxmpeg2videodec ! videoconvert ! omxh264enc target-bitrate=2097152 control-rate=variable ! video/x-h264,stream-format=byte-stream,profile=high,width=720,height=576,framerate=25/1 ! h264parse ! mux. mpegtsmux name=mux ! filesink location=robert.mp4 demux. ! queue ! mpegaudioparse ! mux.

To get the aspect-ratio 16:9 right I had to use VLC which only was able to show this file correctly after resetting the settings.

I guess the last step, streaming over the network, will be a smaller one now.

As soon as I got that working I'll also have a look at the transcoding in TVHeadend earlier in this thread.
The quality of this OMX decoding/coding appears to be good enough to invest some more time in it to get it working straight from TVHeadend.

Gstreamer contains an executable, gst-discoverer-1.0, which can tell you what audio and video-format you need to get your stream decoded.
gst-inspect-1.0 will show you what elements are to be used in the gst-launch pipeline.

Hi
I can confirm that the gst-launch command you provided works also with gst 1.10.3 I have self compiled on my Rpi3.
I'm transcoding a MPEG2 stream from DVB-T, I had to force the video format out from the decoding pipeline, because it seems it's not set correctly with this gst version, see my modified command:

gst-launch-1.0 souphttpsrc location="http://xxxxx::9981/stream/channelnumber/5?profile=pass" num-buffers=-1 ! tsdemux name=demux demux. ! queue ! mpegvideoparse ! omxmpeg2videodec ! video/x-raw,format=I420 ! videoconvert ! omxh264enc target-bitrate=2097152 control-rate=variable ! video/x-h264,stream-format=byte-stream,profile=high,width=720,height=576,framerate=25/1 ! h264parse ! mux. mpegtsmux name=mux ! filesink location=robert.mp4 demux. ! queue ! mpegaudioparse ! mux.

Comparing it to the command I was using, it seems it's confirmed that the issue is with the sync with audio track when attempting to transcode it. Now the problem is that, even if setting the output to a pipeline, the launch command is not that "user friendly", because it must be managed by hand. My goal was to set a IP Mux in TVHeaded that is launching the gst-stream to set the pipeline, so the transcoded channel can be watched with HTPS plugin also.
I try to make some experiment
Bye

Hi
Actually the audio transcoding works also:

gst-launch-1.0 souphttpsrc location="http://xxxx::9981/stream/channelnumber/5?profile=pass" num-buffers=-1 ! tsdemux name=demux demux. ! queue ! mpegvideoparse ! omxmpeg2videodec ! video/x-raw,format=I420 ! videoconvert ! omxh264enc target-bitrate=2097152 control-rate=variable ! video/x-h264,stream-format=byte-stream,profile=high,width=720,height=576,framerate=25/1 ! h264parse ! mux. mpegtsmux name=mux ! filesink location=robert.mp4 demux. ! queue ! mpegaudioparse ! mpg123audiodec ! audioconvert dithering=0 ! audio/x-raw,channels=2 ! fdkaacenc bitrate=65536 ! mux.

Now, merging everything I have set this command that should transcode into a stream, that can be used by http-launch or tvheadend:

gst-launch-1.0 souphttpsrc location="http://xxxx::9981/stream/channelnumber/5?profile=pass" num-buffers=-1 ! tsdemux name=demux demux. ! queue ! mpegvideoparse ! omxmpeg2videodec ! video/x-raw,format=I420 ! videoconvert ! omxh264enc target-bitrate=2097152 control-rate=variable ! video/x-h264,stream-format=byte-stream,profile=high,width=720,height=576,framerate=25/1 ! h264parse ! mpegtsmux name=stream demux. ! queue ! mpegaudioparse ! mpg123audiodec ! audioconvert dithering=0 ! audio/x-raw,channels=2 ! fdkaacenc bitrate=65536 ! stream.

But it doesn't work. With both http-launch and TVHeadend IP Mux, I see that the connection is made, the gst pipeline is started, but nothing is played, and after few seconds, the connection is just closed

Hi
Success, I have a working launch command for http-launch
The funny thing is that I had to add the streamable=true option in mpegtsmux, but gstreamer says that it's an unsupported property....

http-launch 9080 /xyz.ts verbose gst-launch-1.0 souphttpsrc location="http://xxxx::9981/stream/channelnumber/5?profile=mpeg2" num-buffers=-1 ! tsdemux name=demux demux. ! queue ! mpegvideoparse ! omxmpeg2videodec ! video/x-raw,format=I420 ! videoconvert ! omxh264enc target-bitrate=2097152 control-rate=variable ! video/x-h264,stream-format=byte-stream,profile=high,width=720,height=576,framerate=25/1 ! h264parse ! mpegtsmux name=stream streamable=true demux. ! queue ! mpegaudioparse ! mpg123audiodec ! audioconvert dithering=0 ! audio/x-raw,channels=2 ! fdkaacenc bitrate=65536 ! stream.

Now. I have set exactly this command (without http-launch of course) as pipe:// target of an IPTV mux in tvheadend, does anyone know how generate a channel from this IPTV mux????

Hi
Success, I have a working launch command for http-launch

Great! As http-launch uses multiple and unpredictable ports I don't expect it to be our final solution though.

Now. I have set exactly this command (without http-launch of course) as pipe:// target of an IPTV mux in tvheadend, does anyone know how generate a channel from this IPTV mux????

I never used IPTV mux yet. Is that necessary for the RTSP sink? I saw an RTSP-server project in gstreamer github.

I second that goal :) - It would be really great to have all this running inside tvheadend, in one way or the other!

I wish I could contribute, but I don't have the coding skills, so I just sit here an cheer :)

can you write it down for me?

can you recommend another one?
i am using a raspberry pi 3 with raspbian jessie.

RE: TVHeadend Raspberry Pi and Transcoding - Added by Alexander Meinke 12 months ago

Hi Antonio,

nice to see you got a bit stuck (please, that's ironic ;)). Maybe I should have asked more precise, not just "Antonio, what would you do or plan next?".

The Answer could have been "make transcoding live with tvheadend streams". I would like to set the streaming profile in e.g. Kodi or the tvheadend iOS app, set the target connection to my internal dns or external ddns name of pi and watch, shift, record tv with epg and so on in a known environment.

Instead of using a STB with real and pseudo (only bitrate) hardware transcoding that offers possibilities like watching TV from everywhere through your own internet connection at home, we use pi + dvb-x USB adapter + cr. It could also be pc + dvb-x pci card + cr. I think the pi solution would be cheaper than a STB with hw trans. More flexible on new or defect hardware (tuner etc.).
I can see that some provider of internet access - whether cable, radio, dsl or fiber - are going to provide exactly that in one package. Watch tv via app on mobile or on huge, dominating resolution, curved, super flat screen through STB at home.

I think, if we want to get any further on this topic, there needs to be worked on ffmpeg or gstreamer. There is also work needed on the openmax implementation in raspbian. But requires a NDA with SoC manufacturer for video core reference.
So Antonio, if you like to code instead of using code/tools I would suggest that you spent time on ffmpeg or gstreamer. You seem to be not busy enough :-D.

I could need some help on the pipe:// url you mentioned in a earlier post. Is it possible to start a command like ffmpeg or gst-launch with that url? Or do I connect to the streaming url of tvheadend?

Stay tuned

I'm not sure my router accepts those random ports, I often use 22 vpn-tunnels at home while straight communication on the LAN on other ports often goes in error. A vpn-tunnel via MobaXTerm doesn't support UDP though.

If you don't want to build you could use "deb https://dl.bintray.com/djbenson/deb jessie unstable"
that works for RPi2 and 3.

If you want to build (because the build available doesn't contain TVHeadend transcoding) you should teach yourself some git and fetch a more recent source from https://github.com/tvheadend/tvheadend

RE: TVHeadend Raspberry Pi and Transcoding - Added by First Last 12 months ago

Gnag Flow, I had the EXACT same problem. Solution for me was to disable ffmpeg_static in the build (https://discourse.osmc.tv/t/unable-to-build-tvheadend-on-fresh-osmc-kodi17-install/22972).

I still can't find any muxes though, neither can w_scan :|.

Edit: I see now that that actually disables transcoding (whatever that is) and that is actually the subject of this topic. Sorry, I was just trying to help :).

RE: TVHeadend Raspberry Pi and Transcoding - Added by Bernard Konys 12 months ago

I used to have a running gstreamer transcoding from tvheadend source and outputting to a particular port with the following:

gst-launch-1.0 souphttpsrc location= http://192.168.1.53:9981/stream/channelnumber/34 is-live=true ! tsdemux name=demux demux. ! queue ! h264parse ! queue ! omxh264dec ! videoscale method=3 ! video/x-raw,width=640,height=400 ! queue ! omxh264enc inline-header=true periodicty-idr=25 ! queue ! h264parse config-interval=1 ! queue ! mpegtsmux name=mux ! tcpserversink host=192.168.1.53 port=8554 demux. ! queue ! mpegaudioparse ! queue ! mux.

I have no notes of used versions, but will be trying to reproduce during upcoming weeks. Wouldn't the TCP server sink from gstreamer itself be enough for using pipe://?

RE: TVHeadend Raspberry Pi and Transcoding - Added by Andrei D 11 months ago

Hello,

This is the command I use in IPTV Mux for hardware decoding/encoding :
pipe://ffmpeg -loglevel fatal -c:v mpeg2video -i http://127.0.0.1:9981/stream/channelnumber/19?profile=MPEG2 -vcodec h264_omx -preset ultrafast -s 1024x576 -r 29.97 -bf 2 -trellis 2 -b 3500k -bt 700k -acodec copy -metadata service_provider=Digi -metadata service_name=DigiSport2 -f mpegts -tune zerolatency pipe:1

I use a compiled FFmpeg with enabled h264_omx and mpeg2_mmal.I use just pipe://ffmpeg because pipe:///usr/bin/ffmpeg pints to another version of FFmpeg.So after creating an IPTV network,go to muxes,add mux,and at the url put the command.After that go back to Networks,select the IPTV network and force scan it.It will find one service that can be mapped.Do not map with the same number,or use another way to point to the channel(with ticket).Make sure that MPEG2 is alowed for 127.0.0.1 or use username and password.

PS:I use mpeg2video instead of mpeg2_mmal because of bad quality of mpeg2_mmal combined with h264_omx. Maybe someone could point for improvements.In this case the raspberry uses avarage 10% load.Or with htop ffmpeg process varies from 40-60-90% and all 4 cores working splitting that amount.If i use h_264_mmal and h264_omx the results are not that bad but for streaming to a big tv not recomended ,I will use it for mobile.In this case the rasbberry stays under 10%,or 5%.I am not sure that h264_omx supports that flags -preset -r -bf...,but if you don't use -s xxx x xxx it will look very bad.As for profile it won't matter if its pass or MPEG2,I created this for gstream. Sorry for bad language and if I mistaken something.

In the future maybe it will be a way to point tvheadend to use our ffmpeg build, not the static one.In that case we could use transcoding profiles.

RE: TVHeadend Raspberry Pi and Transcoding - Added by Andrei D 10 months ago

Can you please help me?I build tvheadend on raspberry with the built in ffmpeg and the shared one with enabled omx and mmla options.I can se tge h264_omx profile but the output video is green(i can see some pixels or something).I tried all tge presets and olso raspian and osmc.So the transcoding is working but video output is garbage.I fallowed this forum instructions.If I run outside tvheadened the output image is ok.

RE: TVHeadend Raspberry Pi and Transcoding - Added by Jan Kowalski 4 months ago

Hi,,

Anyone is able to change resolution or thick "deinterlace" when h264_omx is set to transcoding? When resolution is set to 0 and deinterlace is disabled, all working fine. But of I want to change resolution to for example 360, picture doesn't appear in "Watch TV".

RE: TVHeadend Raspberry Pi and Transcoding - Added by J N 3 months ago

Firstly, thanks to all your hard work on achiving transcoding on our rpi :)

To get compilation and installation work on my rpi3 with raspbian stretch i had to set "LIBRARY_PATH=/opt/vc/lib".
Without this, compilation failed because mmal and bcm libraries aren´t found by linker.
Strangely enough the command "ldconf -p" list all the needed libraries correctly.

My commands that i used:


export LIBRARY_PATH=/opt/vc/lib
make distclean
./configure --disable-libvpx --disable-libvpx_static --enable-mmal --enable-omx --enable-omx-rpi
make -j5
sudo LIBRARY_PATH=/opt/vc/lib make install

The last command needs "LIBRARY_PATH=/opt/vc/lib" in front of make, because with sudo the env isn´t available.

Hi,

I used J N's commands as a basis and created a tvheadend package with:

LIBRARY_PATH=/opt/vc/lib AUTOBUILD_CONFIGURE_EXTRA="--disable-libvpx --disable-libvpx_static --enable-mmal --enable-omx --enable-omx-rpi" ./Autobuild.sh

the build process went fine, but when I start the new tvheadend version up, it looks like this:

There are no crash lines, so there not a lot to be gleamed from that - looks like an abort.
