  • 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.

  • VP8 Documentation and Test Vector Contributions

    14 octobre 2010, par noreply@blogger.com (John Luther)

    Janne Salonen of the WebM team in Oulu, Finland (formerly On2 Finland) has added a tabular description of the VP8 syntax to the VP8 Bitstream Guide. The new annex provides a concise reference of the elements in the bitstream and we hope will make implementing and testing VP8 decoders easier. The updated document and source can be downloaded from our documentation page.

    We’re working on more improvements to the bitstream guide and invite other community members to help. As with the VP8 code, we gladly give attribution credit to documentation contributors and have added an AUTHORS file to the bitstream-guide Git repository.

    New VP8 Test Vectors

    The Oulu team has also produced some new VP8 test vectors. We analyzed a large set of WebM videos and produced two important corner use cases. The first produces the worst-case memory bandwidth (i.e., lots of global motion, all fractional motion vectors). The second produces the worst-case boolean decoder bin rate over dozens of consecutive frames. These vectors have been added to the VP8 test repository. Our team will consider other corner cases in the next batch of streams we add to the repository.

    How do I automate - downloading anime episodes from Torrent > Encode the videos with ffmpeg or gui > rename (with encoder tag) > upload to Google drive ?
    Should work 24/7. Need help !

  • DirectX D3D11 Hardware Scaling Filter [closed]

    30 décembre 2024, par Dash Santosh

    I'm trying to implement a Hardware scaling filter (vf_scale_d3d11) using the VideoProcessBlt D3D11 DDI, and also add PIX_FMT_D3D11 support for the MediaFoundation Encoder (mfenc).

    


    Initially, there were a lot of "Static surface pool size exceeded".

    


    decode_receive_frame_internal failed = Invalid data found when processing input
Static surface pool size exceeded
get_buffer() failed
thread_get_buffer() failed
decode_slice_headec error
no frame!


    


    This got fixed by incrementing initial_pool_size by 3. Now the following two flows works as expected :

    


      

    1. ./ffmpeg.exe -hwaccel d3d11va -hwaccel_output_format d3d11 -hide_banner -i bbb_sunflower_2160p_30fps_normal.mp4 -hw_encoding 1 -c:v h264_mf -vframes 100 -loglevel verbose sample.mp4 -y

      2. 


    2. ./ffmpeg.exe -hwaccel d3d11va -hwaccel_output_format d3d11 -hide_banner -i bbb_sunflower_2160p_30fps_normal.mp4 -hw_encoding 1 -c:v h264_mf -vf "scale_d3d11=width=1920:height=1080" -vframes 100 -loglevel verbose sample.mp4 -y

      3. 


    


    When I try to call av_hwframe_transfer_data() within the if(encoder_requires_software_frame) block for the following flow, "Static surface pool size exceeded" occurs once again.

    


      

    1. ./ffmpeg.exe -hwaccel d3d11va -hwaccel_output_format d3d11 -hide_banner -i bbb_sunflower_2160p_30fps_normal.mp4 -c:v rawvideo -vframes 10 -loglevel verbose sample.yuv -y

      2. 


    


    Increasing the initial_pool_size to any higher value doesn't seem to resolve this issue. The same error can be observed when the changes are integrated in HandBrake application, even for use cases (1) and (2). Any insights on why this would occur and how to fix this would be appreciated.
