kubuntu 14.04 “VLC does not support the audio or video format “hevc”. Unfortunately there is no way for you to fix this.”


error

I am using the old granny kubuntu 14.04 and it’s brilliant i mean everything was working good until  i get this fucking error that was annoying me , bloody hell , with it’s own stupid sentence:

No suitable decoder module:
VLC does not support the audio or video format “hevc”.
Unfortunately there is no way for you to fix this.

Fuck you silly!

now looking in google you will read you need the silly codec 265 which i should have , so why in the world vlc doesn’t work!? , well  it turns out that you fuckin need this shitty library for vlc  :libde265 

so a rapid search on ppa , which is nasty, i know, for pure souls , but practical for normal  guys and i got this :

https://launchpad.net/~strukturag/+archive/ubuntu/libde265

which leads to this

sudo add-apt-repository ppa:videolan/stable-daily ; sudo add-apt-repository ppa:strukturag/libde265 ; sudo apt-get update ; sudo apt-get install vlc-plugin-libde265

and you have done!

RIGHT CLICK OVER THE SLIDERS … JUST FUCKING THAT AND YOU SEE THIS :

ffmpeg and the message “Thread message queue blocking; consider raising the thread_queue_size option (current value: 8)” ALSA buffer xrun.


i wa trying to do a fucking screencast with this code

ffmpeg -f alsa -ac 1 -ar 48000 -i hw:1,0 -s 1920×1080 -f x11grab -i :0 -r 30 -vcodec libx264 $file

AND I GOT :

[alsa @ 0x22d9660] Thread message queue blocking; consider raising the thread_queue_size option (current value: 8)
[alsa @ 0x22d9660]

ok …. tried to play the file and -,- weirdo audio

solution THE NEW FUCKING PARAMETER

-thread_queue_size 512

ffmpeg -thread_queue_size 512 -f alsa -ac 1 -ar 48000 -i hw:1,0 -s 1920×1080 -f x11grab -i :0 -r 30 -vcodec libx264 $file

AND it works now
