  • MediaSPIP en mode privé (Intranet)

    À partir de la version 0.3, un canal de MediaSPIP peut devenir privé, bloqué à toute personne non identifiée grâce au plugin "Intranet/extranet".

  • Ffmpeg : How to fix error "Please choose an encoder manually" ?

    9 juillet 2023, par Alex

    I am trying to convert a x265 videofile to a x264 format so it can be played on a television. I am trying the following command

    


    ffmpeg -i input.mkv -f mp4 -vcodec libx264 -preset fast -profile:v main -acodec aac -map 0:0 -map 0:1 -map 0:2 test.mp4


    


    to select videos stream 0:0 for video, stream 0:1 for audio and stream 0:2 for the subtitle. However I get an error

    


    Automatic encoder selection failed Default encoder for format mp4 (codec none) is probably disabled. Please choose an encoder manually.
Error selecting an encoder


    


    How to fix this command ?

    


    P.S. I am not an expert in ffmpeg or videos conversion/formats/encodings/audio formats/subtitle formats.

    


    I found EXACTLY ONE google search result with the exact error phrase HERE. And that is not helping as I do not even understand the first sentence.

    


    Below is the output for the first three streams :

    I found a related question HERE whose answer I do not fully understand. However, I tried the following command

    


    ffmpeg -i input.mkv -f mp4 -vcodec libx264 -preset fast -profile:v main -acodec aac -map 0:0 -map 0:1 -map 0:2 -c:s mov_text  test.mp4


    


    but got a new error

    


    Error initializing output stream: Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height


    


    I thought I am defining an "encoder" for output stream "#0:0" (which I think is video), namely libx264. So what else to do here ?

    


    I tried -acode copy and also to use -qp 0 in the command line which all did not work.

    


  • The latest ffmpeg shows "get_buffer() failed". Is this a bug ?

    20 juin 2023, par Ryan

    ffmpeg version 2023-06-19-git-1617d1a752-full_build-www.gyan.dev

    


    i7-1255U, Windows 11

    


    The command line is

    


    "ffmpeg.exe"  -y  -hwaccel qsv  -ss 00:00:03.461  -to 00:00:12.009  -i "input.mov"   -c:v h264_qsv -global_quality 25 -look_ahead 1 -preset veryslow -c:a aac -ar 48000 -ac 2 -ab 128k output.mp4


    


    The "input.mov" is mjpeg.

    


    The result is :

    


    [mjpeg_qsv @ 0000019930260080] get_buffer() failed
[vist#0:0/mjpeg @ 000001993025ff00] Error submitting packet to decoder: Cannot allocate memory

[vist#0:0/mjpeg @ 000001993025ff00] Error submitting packet to decoder: Cannot allocate memory


    


    The messages above repeats many many many times. Finally, it shows :

    


    [vist#0:0/mjpeg @ 000001993025ff00] Error submitting EOF to decoder: Cannot allocate memory


    


    I tried the same command line on a very old version, and it works fine. Is this a bug or there is something new that comes with the new version ?

    


    Thank you for your help.

    


  • Scale with scale_vaapi and than pad, got error. Seems ok without "pad"

    24 mai 2023, par huangda1982

    My computer : customized Linux, haswell
I am trying to scale 1280x720 video to 640x450 in 640x480 frame with black borders. To do so, I run this command :

    


    ffmpeg -v warning -hide_banner -init_hw_device vaapi=vaapi0:/dev/dri/renderD128 -hwaccel vaapi -hwaccel_output_format vaapi -hwaccel_device vaapi0 -filter_hw_device vaapi0 -i 'my_video.mp4' -vf 'scale_vaapi=640:450,pad=640:480:0:14' -c:v h264_vaapi -q:v 18 -profile:v main -level 3.1 -c:a aac -q:a 3 -f mp4 out.mp4 -loglevel verbose


    


    And I got this error :

    


    Impossible to convert between the formats supported by the filter &#x27;Parsed_scale_vaapi_0&#x27; and the filter &#x27;auto_scaler_0&#x27;<br />&#xA;Error reinitializing filters!&#xA;Failed to inject frame into filter network: Function not implemented&#xA;Error while processing the decoded data for stream #0:0&#xA;

    &#xA;

    When I removed the ",pad=640:480:0:14" part, the command continued. I pressed ctrl-c, and did not check the result.

    &#xA;

    "-q:v 18", "-level 3.1" and "-q:a" options seem not work.

    &#xA;
