Thumbs down mplayer video error in RHEL7


Hello LQ,

"mplayer" in RHEL is also giving below error. I don't know how to resolve such video viewing issues.

mplayer: symbol lookup error: /lib64/libavcodec.so.56: undefined symbol: vpx_codec_vp9_dx_algo



Advanced Thanks,
NVyas

The issue is missing dependencies. Maybe CentOS 7 is still new and does not have all packages built for it yet. It looks like you may be able to use fedora 19 packages instead. That is, download the packages you need from a fedora19 yum repo and then install them.

Similar to your other thread:
http://www.linuxquestions.org/questi...l7-4175555515/

..where it seems you haven't tried to look this up. If you did, you'd see that you haven't installed the codecs you need to play videos. Also, you don't tell us how you installed either mplayer or vlc, which is important. Mainly because, unless you are PAYING FOR RHEL, you won't be able to use yum, and have probably missed several dependencies. If you are paying for RHEL, then contact Red Hat support...if you're not, stop where you are and load CentOS.

The best suggestion would be to go back and re-read the installation instructions for mplayer/vlc, and try again.

is this ALSO on the IBM power edge server that you put fedora 20 and ubuntu on ?


for rhel7
contact redhat
pay the $799 USD per year for the server license and then use " yum "

or

install CentOS - it is free
and use yum

It isn't related to RHEL Subscription, as we don't acquire license. This is for RHEL7 64 bit only.

Since you "don't acquire license", then you "don't acquire access to the software you need". Hope you're happy about that too.

AGAIN, as you've been told many times before...if you're using RHEL, then PAY FOR IT, and RHEL is NOT really suitable for desktop use and things like playing videos..it's for SERVERS. Load CentOS if you're not going to pay, and you can use a simple yum command to install things. Don't pay for RHEL, and you can go and load everything from source. Those are your choices.

NO it is a LICENSE ISSUE!!!

if you do not buy the required license then you will not be able to install software that you need for this
-- simple
buy the license and install the prerequisites you are missing

or
install cent and hove a lot less of a problem

but
cent is not a great desktop OS
i run ScientificLinux 6.7 everyday BUT!!!
-- i do not use it as my everyday operating system !!! for that i use a OS BETTER FOR THAT
OpenSUSE 13.2


rhel/cent/sl are GREAT OS's for there intended use

Thumbs up

Hello LQ,

By just asking "video player" related question, I have received inappropriate answers..... I am a certified Linux engineer and working on Main Frame Servers since 8+ years.

Nobody can say that RHEL is meant for Server only. If it is, why they provide such inbuilt "multimedia" feature?

In addition to this, I have local "RHEL7 YUM Server" with rpmforge, epel, rpmfusion and remi repos, which is equally capable to fulfill my requirements.

So, thanks for your valuable support on the said POST and I am happy with mplayer, which has started functioning properly.

your os will be BROKEN very soon
without the RHN updates
the software in the third party repos will be incompatible with the install dvd

i give you about a week or two
then you might not be able to boot the system

have fun !!!!

this is why there is 6 posts telling you to
install centOS
or buy the FING license for redhat

REALLY? So since you're 'certified ', with 8 years experience, why can't you figure out a simple dependency problem, or read the installation notes in the source?

No one said only...and rhel IS designed for servers, with a valid license. You CAN load other things, And if it was 'inbuilt ', why did you have such trouble?

Great...enjoy your unsupported system
