[MPlayer-users] Mplayer not launching M3U playlist from a local file, but works from network file

[Vincent Lambert]

Hello,

I've created a stackoverflow topic with correct coloration and
description of my problem, you can answer here or in the topic as you
prefer.

http://stackoverflow.com/questions/36534875/mplayer-not-launching-m3u-playlist-from-a-local-file-but-works-from-network-fil


I have two identical .m3u files, one on my current directory and another
hosted on a web server on my LAN.

If I try:

-bash-4.1# mplayer -quiet -input file=/tmp/mplayer-control playlist.m3u

It results:

MPlayer 1.0rc2.atmel.1-4.3.5 (C) 2000-2007 MPlayer Team
CPU: ARM

Playing playlist.m3u.


Exiting... (End of file)

And nothing happen. Okai. In another hand if I try:

-bash-4.1# mplayer -quiet -input file=/tmp/mplayer-control
http://192.168.0.101:8000/playlist.m3u

Here is the result:

MPlayer 1.0rc2.atmel.1-4.3.5 (C) 2000-2007 MPlayer Team
CPU: ARM

I was a bit curious about this, I've checked everything (permissions,
cache, ...) tried to host the webserver on my computer instead of LAN...
But it appear that everything is fine when the .m3u is loaded from LAN,
regardless the playlist elements are HTTP links pointing to local or LAN
files.

I really need the previous parameters. But I decided to come back to
basic with:

-bash-4.1# mplayer -playlist playlist.m3u

And as you can see, everything is fine

Do you have any idea why my local file is not loaded when used with the
needed parameters, and works just fine if loaded from LAN (even without
-playlist parameter)?

This looks quite ancient.

I'm on an embedded board with a very dry linux, no gcc, no llvm, no apt, no yum, no way to get a newer version.

For such systems you usually build new versions by cross-compiling so
you don't need any of that.
Apart from that, none of that stops you from testing on a desktop
machine, and if it's fixed bisecting to what change fixed it.
However if you can't update the version it's likely all pointless
anyway, unless you want to rely on having enough luck someone
happens to find a workaround that does not involve code changes...

Why aren't you just using -playlist here?
You're supposed to use that option whenever an input
might be a playlist.

Might be some content-type based auto-detection as playlist.
Local files don't have a content-type...

I just realized I'm not forced to use the API I'm calling but just create a subproccess launching mplayer. I'm loosing some functionnalities (as stop the playlist) but at least it works and I'm convenient with that, thank you :)

You're right, again. I was using the SimpleHTTPServer module from Python. On Python 2.4 (on my embedded computer), the playlist is "octet-stream", but on my LAN server Python is 2.7 and send a correct x-mpegurl

I finally found a workaround, thank you!
