    Lorsque l’on gère plusieurs (voir plusieurs dizaines) de MediaSPIP sur la même installation, il peut être très pratique d’obtenir d’un coup d’oeil certaines informations.
    Cet article a pour but de documenter les scripts de monitoring Munin développés avec l’aide d’Infini.
    Ces scripts sont installés automatiquement par le script d’installation automatique si une installation de munin est détectée.

  • Failed to execute : 0x80070057, when decoding video via ffmpeg with dxva2

    25 mars 2019, par CD83

    I have successfully implemented a video player using ffmpeg. I am now trying to use hardware decoding but I’m facing a couple issues.
    I found a post that I followed as a starting point here : https://ffmpeg.org/pipermail/libav-user/2014-August/007323.html

    I have updated the code that setup the necessary stuff for the decoder. The updated code is available here : https://drive.google.com/file/d/0B5ufHdoDzA4ieVk5UVpxcDNzRHc/view?usp=sharing

    And this is how I’m using it to initialize the decoder :

    // Prepare the decoding context
    
AVCodec *codec = nullptr;
    
_codecContext = _avFormatContext->streams[_streamIndex]->codec;
    
if ((codec = avcodec_find_decoder(_codecContext->codec_id)) == 0)
    
{
    
    std::cout << "Unsupported video codec!" << std::endl;
    
    return false;
    
}
    

    
_codecContext->thread_count = 1;  // Multithreading is apparently not compatible with hardware decoding
    
InputStream *ist = new InputStream();
    
ist->hwaccel_id = HWACCEL_AUTO;
    
ist->hwaccel_device = "dxva2";
    
ist->dec = codec;
    
ist->dec_ctx = _codecContext;
    
_codecContext->coded_width = _width;
    
_codecContext->coded_height = _height;
    

    
_codecContext->opaque = ist;
    
dxva2_init(_codecContext);
    

    
_codecContext->get_buffer2 = ist->hwaccel_get_buffer;
    
_codecContext->get_format = GetHwFormat;
    
_codecContext->thread_safe_callbacks = 1;
    

    
if (avcodec_open2(_codecContext, codec, nullptr) < 0)
    
{
    
    std::cout << "Video codec open error" << std::endl;
    
    return false;
    
}

    And here is the definition of GetHwFormat referenced above :

    AVPixelFormat GetHwFormat(AVCodecContext *s, const AVPixelFormat *pix_fmts)
    
{
    
    InputStream* ist = (InputStream*)s->opaque;
    
    ist->active_hwaccel_id = HWACCEL_DXVA2;
    
    ist->hwaccel_pix_fmt = AV_PIX_FMT_DXVA2_VLD;
    
    return ist->hwaccel_pix_fmt;
    
}

    When I open an mp4 (encoded in h264) video that is HD resolution or less, everything seems to be working fine. However, as soon as I try higher resolution videos like 3840x2160, I get the following errors repeatedly :

    Failed to execute: 0x80070057
    
Hardware accelerator failed to decode picture

    I also start getting the following errors after a few seconds :

    co located POCs unavailable

    And the video is not displayed properly : I get a lot of artifacts all over the video and it is lagging. I checked the first error in the ffmpeg source code. It seems that IDirectXVideoDecoder_Execute fails because of an invalid parameter. Since this is happening withing ffmpeg, there must be something that I’m missing but I can’t figure out what. The only relevant post that I found with this error was because of multithreading but I set the thread_count to 1 before opening the codec.

    This issue is happening on my main computer which has the following specs :

    • i7-4790 CPU @ 3.6GHz
    • RAM 16 GB
    • Intel HD Graphics 4600
    • Windows 8.1

    The same issue is not happening on my second computer which has the following specs :

    • i7 4510U @ 2GHz
    • RAM 8 GB
    • NVIDIA GeForce GTX 750Ti
    • Windows 10

    If I use DXVAChecker on my main computer, it says that my graphics card supports DXVA2 for H264_VLD_*, and I can see that the calls to the Microsoft API are being made (DXVA2_DecodeDeviceCreated, DXVA2_DecodeDeviceBeginFrame, DXVA2_DecodeDeviceGetBuffer, DXVA2_DecodeDeviceExecute, DXVA2_DecodeDeviceEndFrame) while my video is playing.

    I also don’t see any increase of GPU usage (on either computer) between the version with hardware decoding and the version without ; however, I do see a decrease in CPU usage (not as much as I was expecting though). This is also very strange.

    Note that I tried both the Windows release available on the FFmpeg website, and a version that I compiled with —enable-dxva2. I have searched a lot already but I was unable to find what I’m doing wrong.

    Hopefully, someone can help me, or maybe point me to a better example ?

  • Change AVI creation date with ffmpeg ?

    1er novembre 2016, par brock

    As far as I can tell the following ffmpeg command should copy all existing metadata in the input file to the output file and modify the specified field in the output file :

    ffmpeg -i VID_20130502_220104.avi -metadata creation_time="2013-05-02 22:01:04" -codec copy VID_20130502_220104-2.avi

    Instead, it seems to strip all metadata from the output file. Here is the output of a few commands. I am going nuts. I think this should work, but why is it not ?

    Command to edit the creation time :

    ffmpeg -i VID_20130502_220104.avi -metadata creation_time="2013-05-02 22:01:04" -codec copy VID_20130502_220104-2.avi

  • File conversion to mp3 returning failure everytime using flutter package ffmpeg_kit_flutter

    6 novembre 2024, par Sanath balthar

    I am trying to convert a .wav audio file generated from a flutter's text to speech package - "flutter_tts" to mp3 file but it is failing everytime.
I have written the below code for file conversion. I have imported the package ffmpeg_kit_flutter. It doesnt even show why the conversion is failing.
I have looked up in stackoverflow and other sites but could not find any relevant solutions. I am using vscode as editor. I have attached flutter doctor output below as well. Could anyone please guide me ? Let me know if you need more information.
