Ffmpeg open input error number 138

FFmpeg error code -138 on an http url, but I don’t know what it means.

*I’m trying to understand what this error code -138 means from ffmpeg. I am able to play the following url directly in a web browser, as well as using the WPF MediaElement, but it is unable to play using FFME:

«http://commondatastorage.googleapis.com/gtv-videos-bucket/sample/Sintel.mp4»

Please take a look at the small sample project that I attached. It is giving me a MediaFailed event with the error message:

Could not open ‘http://commondatastorage.googleapis.com/gtv-videos-bucket/sample/Sintel.mp4’. Error -138: Error number -138 occurred

• Bug
• Feature Request
• Question
• Not sure

Version Information

• NuGet Package 4.0.270
• Build From Master branch, Commit Enter commit id. Example: 704c482
• Build from Branch Name, Commit Enter commit id. Example: 704c482

Steps to Reproduce

1. Under the «imports» directory of the attachment, download and extract ffmpeg-4.1-win64-shared into the location specified in the «ffmpeg-4.1-win64-shared.txt» file
2. Build the project as Debug x64 (restore the missing FFME packages)
3. Run the app. You will see that after about 5 seconds, MediaFailed event will fire and display the following error message: Could not open ‘http://commondatastorage.googleapis.com/gtv-videos-bucket/sample/Sintel.mp4’. Error -138: Error number -138 occurred

Expected Results

• I expected the FFME MediaElement control to play the http URL mp4 file. The URL works if I copy/paste it directly into Chrome browser. I’ve also tested the URL using standard WPF MediaElement and it is able to play the mp4 file.

Wow, I am super blind! Looking again at the command line execution of ffplay, I can see the error was due to TCP error.

[tcp @ 0000020e13b8d540] Connection to tcp://commondatastorage.googleapis.com:80 failed: Error number -138 occurred
http://commondatastorage.googleapis.com/gtv-videos-bucket/sample/Sintel.mp4: Unknown error

This tells me that the issue is because my workplace firewall is preventing ffmpeg from using that port. However, my browser (as well as the standard WPF MediaElement) is able to use that port, which is why it worked.

Error number -138 occurred #256

I recently set this on on my media server for use with Emby. Everything seems to connect fine but whenever I try to stream a channel, I get the following errors (in locast2plex).

Any help would be appreciated 😃

The text was updated successfully, but these errors were encountered:

locast2plex (L2P), after identifying what variant stream to acquire, uses ffmpeg internally to actually get the transport stream and pass it along

these messages are from that ffmpeg execution and not from the actual L2P code

I have not experienced this particular error code before but will be watching your post progress to find out more about it.

Error code -138 occurs when a connection timeout occurs. This primarily occurs when the TCP packets does not route to the destination address. If it did, then you would either get a connection refused or a connection established. Things that might cause this is a proxy server is in the way so direct comm is not possible. Another is when you have multiple IP addresses and is somehow bound to the wrong IP address. There may be others, but that is where you should start. You can try a few simple things from where the app is running.
telnet hls.locastnet.org 443
If you get a connection, then at least you personally have no routing issue. You can also run a wget command in unix with the url or try it from a browser is see if you can connect. If you can connect, then it is possible it is a configuration issue with locast2plex.

Can you see the last few L2P messages that were produced before the ffmpeg messages began?

It should look something like:
Determining best video stream for
maybe a line or two about found playlists, might mention variant streams
followed by will use xxxxx resolution at xxxxxxbps
followed by a log of the command — — [ ] «GET » 200

I am interested in what was

When you start L2P, can you go to a browser and enter :6077/help
which is not a valid L2P command but is known to return a 501 not implemented.
Please note that should be replaced by the ip address of where L2P is running,
like 192.168.1.10 or some such.

your hls.locastnet.org interests me, as I cannot find that string in the L2P source code. I had a quick look at the URLs that are used to get playlists in my own dma and they do not have hls within them.

Can you share some of your configuration? Are you using Docker? Be sure to obscure your userid and password.

I don’t run EMBY, so that is a black box to me.

L2P works well for me and I have had very few issues after running it six months or so. Let’s see if we can get it working for you, too.

I did not know that these posts throw away anything inside lessthan and greaterthan, which will make my previous post a little hard to determine, since I used that a few times. It should be obvious where I meant to put ip address, like before the :6077, and if it is not, then post again and we’ll try again.

Well. It works now lol

I didn’t change anything. I got tired of messing with it and let it sit overnight and now everything is working.

I just checked my log file and I noticed I’m constantly getting messages such as.

These are all sources using DroidCam on a phone, and the phone is not currently broadcasting, or cameras pointing to 3D printers, which are currently turned off.

Having this in the log is not really a problem, other than it could be hiding other real issues inside the spam, so it would be nice if I could keep my log tidy.

I suspect I could «Close File when inactive», but this will give me a delay when I show the source, and I like to have them slide into veiw.
Is there a way of preventing the log message from appearing, but still allowing the feed to be quickly shown when it is available?

FFmpeg reports Error number -138 occurred while playing youtube videos #7519

Important Information

Provide following Information:

• Windows Version Win10 1909(18363.693)
• Source of the mpv binary https://sourceforge.net/projects/mpv-player-windows

Reproduction steps

Run mpv «https://www.youtube.com/watch?v=sY3peHvDN8I» —ytdl-raw-options-append=proxy=»http://127.0.0.1:1080″ —script-opts=ytdl_hook-try_ytdl_first=yes —no-config

I have to use a proxy, or I can’t even visit youtube

With youtube-dl(2020.03.06), I can download the video

I have read some similar issues like unosquare/ffmediaelement#301 and ytdl-org/youtube-dl#18178 and tried to solve it by changing firewall settings but it doesn’t work

Expected behavior

The video can be played

Actual behavior

FFmpeg reports error

Log file

Sample files

Any youtube video like this

The text was updated successfully, but these errors were encountered:

Unless something changed recently, IIRC the youtube-dl proxy settings don’t apply to the ffmpeg http downloader which mpv uses. Try setting a $https_proxy var before launching mpv.

Yes, it will work if I set an environment variable.

This is useful for geo-restricted URLs. After youtube-dl parsing, some URLs also require a proxy for playback, so this can pass that proxy information to mpv.
[cplayer] Set property: file-local-options/stream-lavf-o=<«http_proxy»:»http://127.0.0.1:1080″> -> 1

I thought the proxy was set by mistake according to the manual and log(may because of my poor English).
Is it worth noting in the manual?
