mkvserver_mk2's Issues

URL read error: -57

I get a URL read error: -57 most of the time if I leave it running too long, sometimes if I refresh the url (with port included) specified in server2.c. This also sometimes occurs if the browser download prompt is cancelled. This happened sporadically as it happens almost every other time I test. Sometimes, while not downloading, the error just occurs while the tab wasn't open. When this error occurs, the server shutsdown and needs to be restarted. I was testing this on a Firefox client on installed on Windows 7 and the server is FreeBSD 12.0 where the executable was compiled as well.

This is some of the output I get before the error occurs. The error -54 error you see is due to cancelling the download prompt:

EDIT: I tested streaming with VLC and it gave the error after jumping forward in time while streaming.

Change port

How can I change the port used to stream?

I want to serve many files from the same server...can't do that without using a different port

Thanks!

Suggestion for streaming client (README)

Instead of -c libx264 use -codec:v libx264.

Is there any more detail on what OS or what ffmpeg version I should be using? Readme just says ffmpeg should be "recent".

How about it's performance? CPU usage low enough?

Hi I’m looking for a RTSP server on MIPS architecture, I’v tried ffserver. On ffserver, it takes about 5% of CPU for every channel. It’s pretty high. Is there alternative ?
Thanks!

How to consume generated stream?

Thank you very much for this project!

I would like to create web page and display the stream generated by this server but currently I don't how. I use the last example (I had to add -f matroska to ffmpeg call) and in server output I don't see any hints how to consume the stream -- I am not even sure if the stream is correctly created, because I see periodically "Error or timeout, ret: -110" error.

So, my question is -- what is the minimal setup/example to consume the stream?

Playback on VLC won't work for some sources.

I have tried with a local mkv and it work great.
I have tried with a remote mkv (http://****.mkv) and it work great.

I have an online video stream that seems to start ok but playback never starts in VLC (it also never seems to time out).

Here is the start up of it:

Here is the FFMPEG output:

  Duration: N/A, start: 20541.882667, bitrate: N/A
  Program 1 
    Metadata:

    Stream #0:1[0x101](eng): Audio: aac (LC) ([15][0][0][0] / 0x000F), 48000 Hz, stereo, fltp, 66 kb/s

Any ideas how to fix this or why it won't work?

Embed Stream

Hello,
I have try you server, and with vlc and ffplay I'm able to play the stream. But I would like to embed the stream to. Is this possible?, with something like this:

<video id="myStream" class="video-js">
      <source src="http://192.168.0.91:8080" type="application/x-mpegURL">
</video>

Is this a replacement for ffserver?

I'm trying to set up ffmpeg on a Raspberry Pi 3B+ to record 2 USB webcams (/dev/video0 and /dev/video1) to disk and simultaneously stream them live to connected web browsers (presumably using <video> elements). ffserver sounds like what I need, except it appears to be discontinued. Can mkvserver_mk2 do this? How would I set it up?
I'm wondering why ffserver is no longer offered, as it seems like it filled a common need.

README doesn't contain advice on how to minimize lag

I'm filing this as a documentation bug, rather than a bug with the code, which I assume supports this.

I am / was considering using this project for a near-realtime streaming application, but I'm seeing lag of about 60 seconds between the source (screen recording with ffmpeg) and seeing the result on VLC. So far as I can tell, almost none of this is network lag. I've tried tinkering with the buffering constants in the source without success. Is there any way to get lag down below 5 seconds or so?

Can't compile on ubuntu 22.04

How can i fix it? I have succesfully installed "ffmpeg" via Homebrew and not found "ffserver", and decided to install this software.

URL read error: Transport endpoint is not connected

I'm trying to host a live stream on a website, but first testing by streaming a video file locally. However, trying to run it results in this ending the stream right after it starts. What is the fix for this? Thanks :)

How to view the generated stream via ffplay?

I'm able to live stream webcam via ffmpeg to mkvserver
On Client :
ffmpeg -f avfoundation -framerate 30 -i 0 -b 900k -f matroska -r 20 tcp://<ip-address>:<port-number>
On Server :
nc -l <port-number> | ./server

I've tried : ffplay tcp://<ip-address>:<port> to view the stream but got the Connection timed out error.
Please suggest a way to view the stream on the server.
Thanks for any help!

rtsp usage

Hello, I'm trying to implement a rtsp server with ffmpeg and I was wondering if your server suports rtsp.
Thanks.

double free at second segment

This happens at the second segment being sent to a client. The buffer Client.avio_buffer of said client points to the address allocated in publisher.c:publisher_add_client(). This address is av_free()'d by avformat_open_input().

Feature request: Spawn process on connection

Hello,

I'm using gstreamer to stream from v4l. Currently, it consumes about 40% CPU, regardless if somebody watches or not.

It would be nice to specify a command that is executed as soon as the first viewer connects, and is killed as soon as the last viewer disconnects.

I hope it's understandable what I mean..

Current:

/root/gstreamer.sh | /root/mkvserver_mk2/server

Proposal: Something like
/root/mkvserver_mk2/server --exec /root/gstreamer.sh --timeout 30

It doesn't compile on FreeBSD
