  • AForge.Video.VideoException : Cannot allocate video picture

    23 octobre 2015, par user5389242

    I’m trying to convert images into a video file, but I’m getting the following error :

    An unhandled exception of type ’AForge.Video.VideoException’ occurred in AForge.Video.FFMPEG.dll

    Additional information : Cannot allocate video picture.

    The error occurs on writer.Open :

    writer = new VideoFileWriter();
    
writer.Open("/output.avi", width, height, 30, VideoCodec.MPEG4, 1000000);

  • SVT-AV1 : After encoding the video seeking is very bad in any video player (even HTML5)

    18 juin 2020, par Viktor Machnik

    i am using SVT-AV1 and FFMPEG to encode Videos into the AV1 video and opus audio codec (.webm), it works fine, except that the video seeking do not work really (extremly bad). When i seek, the CPU useage jumps up and it takes up to minutes until the seeking process finishes.

    



    Here is how i encode the videos :

    



      

    1. Convert any video into yuv : ffmpeg -i  -preset veryslow -level 6.2 .yuv

      2. 


    2. First AV1 run svt-av1 -i '.yuv' -w  -h  --fps  --rc 0 -q 30 --preset 8 -b '.\output1.ivf' --output-stat-file '.\stat_file.stat' --keyint 1 --enable-restoration-filtering 1

      3. 


    3. Second AV1 run svt-av1 -i '.yuv' -w  -h  --fps  --rc 0 -q 30 --preset 3 -b '.\output.ivf' --input-stat-file '.\stat_file.stat' --keyint 1 --enable-restoration-filtering 1

      4. 


    4. Get source video audio in opus codec ffmpeg -i  -c:a libopus -vn -preset veryslow -level 6.2 output.ogg

      5. 


    5. Get final .webm video ffmpeg -i output.ivf -i output.ogg -c copy output.webm

      6. 


    



    I have allready tryed to play with the —keyin option, also just letting it away and use the encoder default, but the results are always the same. (--keyin 1 seems to work better than without this option, but also very very bad)

    



    What am i doing wrong ?

    



    Extras : I am using Windows 10 with downloaded version of SVT-AV1 and FFMPEG (I just renamed the SVT-AV1 Encoder .exe file to be svt-av1.exe). Used CPU is Ryzen 9 3900X
