How To Install Gstreamer Windows Updates
Is a really great framework for creating multimedia applications on Unix environments and specially useful when dealing with multimedia Embedded Projects. Interfacing with this Embedded Applications from other platforms, rather than Linux, is often a requirement so this is a quick reminder about how to set up gstreamer on Windows OS. The steps are really easy: Download the latest windows compiled version of gstreamer (1.0.10 atm) for your platform 32/64 Once installed check the following environment variable are set to their proper locations.
Gstreamer allows you to stream video with very low latency – a problem with VLC currently. The catch is that you need need gstreamer on the client used to view the stream.
Getting GStreamer How do I get GStreamer? Generally speaking, you have three options, ranging from easy to hard: binary packages for Windows.
Gstreamer is a development framework not a media player and there isn't a way to stream so that common players such as VLC can display the stream (without users having to install complex plugins). Razer Deathadder Driver Without Synapse. So, gstreamer can provide an excellent low latency video link, which is great if you are techy enough to set it up at both ends, but its no good if you want to directly stream so that Joe public can see the video on a web site for instance. Setting Up The Raspberry Pi To Use gstreamer You need to edit the sources.list file so enter: sudo nano /etc/apt/sources.list and add the following to the end of the file: deb. Main Press CTRL+X to save and exit Now run an update (which will make use of the line just added): sudo apt-get update Now install gstreamer sudo apt-get install gstreamer1.0 To Stream The Video From the Raspberry Pi Enter this on the command lne: raspivid -t 0 -h 720 -w 1080 -fps 25 -hf -b 2000000 -o - gst-launch-1.0 -v fdsrc!

To View The Stream There's a lot of resources around for this. Seems to be pretty easy on Linux, OK on a MAC and harder on Windows. Apparently streaming from RPi to PRi works really well. I got this on server side: raspivid -t 0 -h 720 -w 1080 -fps 25 -hf -b 2000000 -o – gst-launch-1.0 -v fdsrc!
Rtph264pay config-interval=1 pt=96! Hi, I have been trying to use raspberry pi 2 to transcode videos that I record using mythtv on another machine. After a lot of trial and error I think I have finally got a successful setup. The important things I needed were: 1. At least a 3amp power source 2.
Gpu memory at least 256MB to prevent gst via the OMX plugin from failing for lack of memory 3. Edit /etc/sysctl.conf: # rpi tweaks vm.swappiness=10 vm.min_free_kbytes = 16384 to ensure no failure for lack of RAM 4.
In gst-launch-1.0 use: queue max-size-bytes=0 max-size-buffers=0 max-size-time= to prevent the gst pipeline from stalling for lack of synchronized data 5. Omxh264enc control-rate=1 target-bitrate=15000000!
H264parse I want high quality video, in matroska container to be able to stream using my dlna server to my TV 6. There are is a bunch of other things I do with the mythtv source file to preserve subtitles and remove commercials but that’s not for here.
What version of raspbian are you using? I installed the newest version and an apt-get update and installed gstreamer1.0.
However, I am just getting a still picture. I have tested the raspvid locally on the pi and the video works fine. However, when I stream through gstreamer and launch gstreamer from windows, I just get a single still frame.

Autovideosink What issues did you run into with a power supply less than 3 amps?
Hopefully, you had the same issue with a single still frame and no stream? Your comment inspired me to get a bigger power supply.
I am just looking for your input at failed attempt and what the resolution was. Thanks for any input! Sorry for not replying earlier. I have latest raspbian and gstreamer1.0 from the raspbian repository, 1.2. I have had some issues with varieties of rpi-update of firmware, but those guys have fixed them quickly. Mine is a raspberry pi b, too.
The power supply issue: when the the cpu was fairly heavily engaged transcoding, the pi turned off or froze completely. Improving the current available fixed that.
And I wasn’t powering anything else, no usb, no mouse, no keyboard, only the nic. I have only been using it to transcode videos, no still frames. I had no luck with the config-interval switch on h264parse, I stopped using it all together. As I say, I am now using the dynamic memory split. Seems better to me.
John, thanks to you I have managed to stream my tvheadend recordings to rtmp successfully. This is my pipeline: gst-launch-1.0 filesrc location=video.ts! Decodebin name=demux demux.! Queue leaky=1 max-size-bytes=0 max-size-buffers=0 max-size-time=0! Audioconvert dithering=0!
Flvmux name=mux streamable=true! Rtmpsink location=rtmp://localhost/recordings/test demux.! Queue leaky=1 max-size-bytes=0 max-size-buffers=0 max-size-time=0! Omxh264enc control-rate=1 target-bitrate=2000000! Audio and video works perfect, but if there is more that one audio track I always get the first one. Also it looks like I get the first subtitle track as well, but no subtitles shows up in VLC. Do you know how to chose the correct audio track, and how to mux the correct subtitle track?
I’m afraid I don’t off hand. But I did see some conversations about that a long time ago.
I will have a look for you. Subtitles are tricky.
What codec does your original use for them? For mine, they are teletext subtitles and gst does not have a decoder for them. The teletext protocol uses pages to identify the appropriate text and can be very variable according to the transmitter. So I have to use a subtitle extractor that comes with myth TV. And then recombine them using mkvmerge.
It is a long and cumbersome process but it does work. John, Thanks for a quick response and thanks for helping. My goal is to get the english audio track and the finnish subtitle track. I finally managed to get the right audio track. In my pipeline I have to use tsdemux name=demux instead of decodebin name=demux Then for the audio i use demux.audio_1031, where 1031 is the last four numbers in the stream ID from gst-discoverer.
Subtitle tracks are chosen the same way. I have tried to implement the information found in these links: But I don’t have enough knowledge about how gst-launch works to implement it into my project. This is as far as I have come, but I don’t know where to put this “r.” to make the subtitles overlay the video: gst-launch-1.0 filesrc location=video.ts! Tsdemux name=demux demux.audio_1031! Queue leaky=1 max-size-bytes=0 max-size-buffers=0 max-size-time=0! Flvmux name=mux streamable=true!
Rtmpsink location=rtmp://localhost/recordings/test demux.! Queue leaky=1 max-size-bytes=0 max-size-buffers=0 max-size-time=0!
Omxh264enc control-rate=1 target-bitrate=2000000! Queue leaky=1 max-size-bytes=0 max-size-buffers=0 max-size-time=0! Dvbsuboverlay name=r Do you have any ideas? I’m still not getting transcoding with rpi 2 and gstreamer to work 100% My problem is that the ram is filling up.
Right now I have two queues, one for audio and one for video. I have set ‘no limit’ for how large the queues can be. When transcoding, everything goes fine until the ram is filed up and the pi crashes (takes about 25 minutes for 720p h264 video.) When I try the max-size-time= setting for the queue the output file will look good for 5 seconds, then frames are lost every 5 seconds. I have also tried the leaky=1 and leaky=2 settings for the queue, but no luck. Why doesn’t the data that have already been processed by the encoders/decoders get released from the ram? There is no point storing everything in the queue until gst-launch-1.0 has shuts down. I hope someone can explain these things to me.
