At the moment plugin-initialization can only happen one time in the life-cycle of castnow. This is because some plugins start HTTP servers which would need to be closed before the player can be booted again. Also peerflix must get shutdown and the transcode process must be ended.

The solution is to introduce some sort of shutdown-process. Maybe a "close" event could be emitted on the ctx object. The plugins would listen to this event and clearup their stuff. Only problem is that this would need to be sort of async with next()/done() functions and stuff. Otherwise we would not know when the player is fully un-initializated.
This is also important for the Web UI ( #29 ) to work since castnow acts as an ongoing process in that scenario.

My host computer is running behind a vpn, which I think would be a good idea when streaming torrents, can't find my chromecast, tried using --myip with both ip that my vpn is behind and the vpn my router is behind. Still trying to troubleshoot, but I was hoping someone had a solution.

Casting youtube http links works, but when using an https link, the app doesn't work.

No error, nothing.

Not sure what can it go wrong, but here it goes.

This doesn't do anything for me. I'm on Ubuntu 14.04. Installed npm then did npm install castnow -g. Had to also install node. Once I did that I tried castnow

Whenever I cast a file with the --tomp4 option, the state constantly says "Buffering..." even though the video is playing smoothly. In addition, this doesn't let me use any of the key-bindings to pause or seek.

does not play local and web subtitles, will continue to play video though.

my command for the web video with local srt file looks like this:

Debug is also not a recognized command when I try to input

DEBUG=castnow* castnow --subtitles </path to srt file>

Would it be possible to add data to the screen that is being cast to, such as what is currently playing.

Seems like only audio works when playing youtube videos at the moment.
Can anyone confirm this? Current guess is that they changed something within the protocol.

To make

castnow http://mirrorblender.top-ix.org/peach/bigbuckbunny_movies/big_buck_bunny_1080p_surround.avi --tomp4

The transcode plugin has certain limitations at the moment:

• Some player controls like play/pause/seek don't work while transcoding
• There is no playlist support

Improvements that could be made:

• Instead of transcoding on the fly and piping the output directly as HTTP response to the user the output should be piped into an temp file which acts as some sort of buffer. While the transcoding is in progress the temp file can be piped to the user as HTTP response. This way play/pause/seek should work again.
  The temp files could be deleted on process.end().
• Don't know if this is too much magic: Instead of the --tomp4 option files could get transcoded based on the file extensions. For example .avi and .mkv would be transcoded but not .mp4 or .mp3. This way we should also be able to create playlists with files which need transcoding.
• Users should get an error message displayed if they try to transcode a file but don't have ffmpeg installed.

It would be nice to toggle subtitles through a key. Maybe with v-key ("VTT") since the s-key is already in use.

I've tried different files from different sources including magnet links and nothing seems to work. As an example I can't get this to work:

castnow https://archive.org/download/ThemeFromShafthip-hopRemixVideo/ThemeFromShafthip-hopRemixVideo_archive.torrent

I also tried putting the link in quotes and I tried to just download the torrent and run it that way. I can't tell that it is doing anything, is there a log I could tail?

We could parse the package.json to retrieve the current version.

Saw this in the subtitles plugin:

https://github.com/xat/castnow/blob/master/plugins/subtitles.js#L34

It works fine with other video files mp4 and mov but mkv don't seem to have sound.

For example if someone is using the --tomp4 parameter and dosn't have ffmpeg installed.

Simon,
I understand that new "Issue" is not the right place to share ideas but I thought we can use it for now.

After using castnow to stream online content I'm amazed how well this works. I currently have it loaded on one of my Debian Wheezy box that I have on LAN. This way I have a central place that I can go to and start the stream. The box is CLI only.

The immediate idea I had was to have castnow-webserver which would serve web interface around castnow so no ssh would be needed to start the stream. What do you all think?

npm ERR! Error: 400 Bad Request

When the playback is paused for more than about 5 minutes, resuming it makes castnow switch to idle.

Once it is idle, is there any way to continue the playback, without reopening castnow with an approximate --seek?

My machine has multiple IP addresses (I've got virtualization software installed). I noticed castnow picks up the wrong IP address, thus initially it was never working for me .. I noticed that if I pass the --myip parameter, it does work (and it's awesome)

castnow should automatically pick the IP address that falls within the network of the chromecast device.

1. Could you add a "path" option where media files are stored?
   peerflix: .alias('f', 'path').describe('f', 'change buffer file path')
2. Delete media files on exit.

This is my assumption and I can be completely wrong but I came across URLs with no file extensions that will not play using castnow.

The direct link to the file looks like this:

0:{src:'http://<IP_here>/token/video/vod/<current_time>/<current_date>/<some_number>/f7b03ddc-03a3-484d-bc76-2330ed9a2801', type: 'video/mp4'},

castnow --device "Living room" http://<IP_here>/token/video/vod/<current_time>/<current_date>/<some_number>/f7b03ddc-03a3-484d-bc76-2330ed9a2801

I get the following:

Launching ...
Loading ... < app gets loaded on the TV

Here I'm being dropped to the prompt with no error message. App stays loaded on the TV

There is no problems when the file gets downloaded first:
wget http://<IP_here>/token/video/vod/<current_time>/<current_date>/<some_number>/f7b03ddc-03a3-484d-bc76-2330ed9a2801

castnow --device "Living room" f7b03ddc-03a3-484d-bc76-2330ed9a2801

I get the following:

Launching ...
Loading ...
Buffering ...
Playing ...

Also there is no problems when I use Chrome browser to go directly to the link:
http://<IP_here>/token/video/vod/<current_time>/<current_date>/<some_number>/f7b03ddc-03a3-484d-bc76-2330ed9a2801

The video gets loaded in the Chrome tab and can be played in Chrome browser as usual.

Here is a different URL from the same website that works with castnow. This one has the extension.
The direct link to the file looks like this:

This is when using the latest 0.4.5 version. Let me know if you need any more debug.

Chromium doesn't support AC3, which means that MP4/MKV files with AC3 codec will be played with no audio. This can be solved by piping the file through ffmpeg using the acodec libmp3lame param, as Chrome supports MP3.

Suggestion:
Detect audio codec in local file, and start the local file using --tomp4 --ffmpeg-acodec libmp3lame

I've got an error and it's seems to be an error from ffmpeg or transcoder.
I use avconv (ffmpeg will be remove from Debian and it's removed from Ubuntu 14.04)

Hi,
what can be the cause for that?
I get the loading bar on tv but nothing happens. I tried with mp3 and mkv with --tomp4...

Hi, it would be great to be able to switch between different audio tracks. Perhaps it is a problem with the Chromecast stick itself, which seems to be capable of it. I am no expert on the mkv container format, but perhaps there is the ability to change the order of the audio tracks just inside the container description. Castnow could then send a slightly manipulated mkv container in the beginning of the video file to the Chromecast stick?

PS: Great application, thanks a lot!

Hi,

First compliments for the work so far, it's a great concept and what's implemented so far works very well for me.

The key feature for me would be to be able to script my HTPC to launch live tv channels. The provider I use has iOS and Android mobile apps and a web interface which all have chromecast support built in. Under OS X I can go to a URL, click the chromecast button and I get full screen video (e.g. not just a cast of the full tab).

When I try to load the URL with castnow I get:

DEBUG=castnow* castnow http://zattoo.com/watch/bbc-one

I'm not sure if Zattoo is accessible internationally. In any case it's behind a user login. Sorry if there's not much for you to work with - but I hoped you might be able to advise of any general approach to get castnow to handle a web page which flawlessly supports chromecast from a browser?

thanks!

I tried it with a magnet link.

(castnow magnet --subtitles C:\path\to\file.srt)

Entire thing says this:

'dn' is not recognized as an internal or external command,
operable program or batch file.
tr: two strings must be given when translating
tr: unrecognized option --subtitles' Trytr --help' for more information.

Edit: Looks like it works with local video files, not with magnets.

Does castnow playback .avi files? When I try to stream an .avi file, castnow seems to start playing the file then stops. castnow works with other file formats I have.

I've one problem... its working from WIFI to WIFI, but won't work from LAN to WIFI.
Any ideas?

On Fedora 20, fully up to date. It installs correctly. It stalls forever "scanning". Passing --device 'the right name' did not help. Neither --verbose nor --debug flags shed any light.

Chrome web browser with the chrome cast extension finds the Chromecast immediately and can cast a tab without problem.

The machine has a single network interface active. Passing --myip did not help either.

The machine has a physical network (1Gbps) to the AP where the Chromecast is associated. Other machines also connect the Chromecast over the same network without problem.

What can I do to help debug this? I'm a fairly competent programmer, but not familiar with the node.js stack in the least.

thanks!

Currently issuing the following commands result in an error (exception):

castnow
castnow -h
castnow --help

I think most people are used to getting the 'usage' printed out in case of errorneous input. This would also be a good way to educate the users about options (e.g., --tomp4).

From Fedora 20, fully up to date, I can use castnow with a youtube url, but not with a local MP4 file.

Using --debug, the last status printed is "player status: ready". Not sure how to debug this further...

I guess jumping to the next video only works for youtube videos if the player is in idle-state.
