• No lib64 directory in python virtualenv with WSL

  21 décembre 2019, par Nick

  I am using WSL on windows 10. I created a python3.6 virtual environment using virtualenv. When trying to import the "arcade" library I’m getting the following error :

  Unable to find match for ffmpeg sound library at expected location: /home/nick/python-virtualenvs/final_projects/lib64/python3.6/site-packages/pyglet_ffmpeg2/linux_x86_64/libavcodec.so.58.*

  Although I have pyglet_ffmpeg2 in lib sit packages, it turns out I don’t even have a lib64 directory. I have confirmed that this is 64-bit python using :

  print ctypes.sizeof(ctypes.c_voidp)

  It actually looks as though I don’t have 64-bit packages at all, even within base python for example, there is no /usr/lib64/.

  Anyone have any ideas ? My instinct is this is a WSL quirk, or at least something specific to how I have it installed. A quick google search did not provide any answer.

• ffprobe failed to execute command

  31 août 2020, par Ted Bed

  I'm trying to get a frame from a video in a temp location but I get an error like this :

  


  Uncaught Alchemy\BinaryDriver\Exception\ExecutionFailureException: ffprobe failed to execute command '/usr/bin/ffprobe' '/tmp/phpfwEh9u' 


  


  Which is weird because I have another script that does the exact same thing but there is no error. Are there any reasons for why this could be happening ? Could there be any factors causing this in my script :

  


  $sec = 1;
$movie =  $filentmpname;
$thumbnail = 'thumbnail_uploads/' . $imfileid;

$ffmpeg = FFMpeg\FFMpeg::create();
$video = $ffmpeg->open($movie);
$frame = $video->frame(FFMpeg\Coordinate\TimeCode::fromSeconds($sec));
$frame->save($thumbnail);


  


• ffplay cannot position multiple players at different locations on the screen

  15 avril 2020, par smartblonde

  We would like to use ffplay for monitoring live streamed video, instead of VLC. We are hitting some limitations. DO we know work arounds ? The first issue is that we cannot position ffplay's windows at different locations on the screen via command line params. We've tried options on the command line of -x,-y,-top,-left,-w and -h, -width and -height. It appears that only -x and -y are recognized by ffplay as valid Options, regardless of the corresponding values assigned to each option. Also, -x seems to be the "width" of the player, and -y the "height" as opposed to the x and y location of a corner of the player on the screen. The other options seem to return unrecognized option. Is there a standard set of options available on all builds / OS download releases that will work to allow us to place the players around the screen ? Thank you !
