  • Creating farms of unique websites

    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

  • Automated installation script of MediaSPIP

    25 avril 2011, par

    To overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
    You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
    The documentation of the use of this installation script is available here.

  • ffmpeg Decoding Progress during Frame Extarction

    4 avril 2013, par Isantipov

    I scan input video to extract certain frames using ffmpeg's select filter. The selection is based on a complex creteria and the number of extracted frames can't be predicted (I'm doing scene detection, but this can be something different - e.g. selecting all the I frames, etc).

    What I need is to display the percentage of scanned (decoded) video (e.g. 10% or 90%).

    I tried several ways to do this parsing console output as people usually do when dealing with encoding, but it doesn't help with the progress of scanning (e.g. Can ffmpeg show a progress bar ? or ffmpeg Progress Bar - Encoding Percentage in PHP)

    ffmpeg -progress sceneProgr.txt -i input.wmv -vsync passthrough -an -vf select='gt(scene\,0.2)',showinfo scene%%05d.png

    The output this produces is as follows :

    <..>    
    
frame=    0 fps=0.0 q=0.0 size=N/A time=00:00:00.00 bitrate=N/A    
    
n:0 pts:16550 pts_time:16.55 pos:4205325 fmt:rgb24 sar:0/1 s:640x480 i:P iskey:1 type:I checksum:95895BC9 plane_checksum:[95895BC9]
    
frame=    1 fps=0.7 q=0.0 size=N/A time=00:00:00.00 bitrate=N/A    
    
n:1 pts:24591 pts_time:24.591 pos:6685325 fmt:rgb24 sar:0/1 s:640x480 i:P iskey:0 type:P checksum:FF4CC015 plane_checksum:[FF4CC015]
    
'frame=...' and 'n:...' lines are repeated for each of the extracted frames.

    Both frame=... and n:... lines refer to the numbers in the output and therefore can't be used to calculate progress the way people usually do this (as I can't predict how many frames will be found beforehead and besides, they are not uniformly spread across the input video).

    If I specify -progress progress.txt parameter, the progress.txt file is as follows :

    frame=5
    
fps=1.2
    
stream_0_0_q=0.0
    
total_size=N/A
    
out_time_ms=43209833
    
out_time=00:00:43.209833
    
dup_frames=0
    
drop_frames=0
    
progress=continue
    

    

    
frame=6
    
fps=1.3
    
stream_0_0_q=0.0
    
total_size=N/A
    
out_time_ms=52252200
    
out_time=00:00:52.252200
    
dup_frames=0
    
drop_frames=0
    
progress=continue
    

    
frame=6
    
fps=1.2
    
stream_0_0_q=0.0
    
total_size=N/A
    
out_time_ms=52252200
    
out_time=00:00:52.252200
    
dup_frames=0
    
drop_frames=0
    
progress=continue

    New portion is written approximately every second and refers to the last extracted frame.
    Which is somewhat helpful as out_time refers to the last extracted frames' position in the input video, so I can calculate the progress of the scan from it as

    progress = out_time_ms/total_input_time

    But this is not ideal as it will be updated only when the new frame which matches the select criteria is extracted. So, If I have a large portion of video with no matching frames, the progress won't change for a lot of time.

    Wrapping-up :

    I am looking for a way to calculate the progress of video scanning when using select filter.

    Any ideas are strongly appreciated.

    lavc/vaapi_hevc : fix scaling list duplicate transfer issue.

    scaling list is already transfered to raster scan during head parsing,
    
so no need to transfer it again.
    

    And after this fix, FATE test SLIST_A_Sony_4/SLIST_B_Sony_8/
    
SLIST_C_Sony_3/SLIST_D_Sony_9 will pass in i965/Skylake.

    af_hdcd : Warn if there is any resampling or format conversion in the link chain

    HDCD is only encoded in s16@44100Hz. Scan the chain of AVFilterLinks
    
for any resampling or format conversion/truncation that might cause
    
problems for the filter and issue warnings.
