    crystalhd : Fix up the missing first sample
    

    Why on earth the hardware returns garbage for the first sample of
    a decoded picture is anyone’s guess. The simplest reasonable way
    to patch it up is to copy the first sample of the second line. This
    should result in the correct chroma values (because the data was
    original 4:2:0 upsampled to 4:2:2) even if the luma is isn’t.

    14 février 2018, par Vimal Mistry

    I am working in Laravel 5.4 project. I have to use ffmpeg for generate thumbnail from videos. I am using cloudlinux on my server. I installed ffmpeg in my server.

    It is working fine in ssh bash. All the functionality working there.
    But problem is when I am trying to call from inside laravel using exec() or shell_exec(). Its returns error like "sh : ffmpeg command not found". I tryied full path also like "/usr/bin/ffmpeg -etc-". In that case ’No file or directory found’ errors shows. While it is installed in this path. and working in bash command.

    Please give some suggestion or solution for it.

  • C++ : Encoding H264 with FFmpeg, unable to set preset

    3 janvier 2023, par Mateusz Wójt

    I'm trying to encode H.264 movie with FFmpeg/libAV, when I try to set the codec preset the return code indicates an error :

    


    ...

mContext.codec = avcodec_find_encoder(AV_CODEC_ID_H264);

mContext.stream = avformat_new_stream(mContext.format_context, nullptr);
mContext.stream->id = (int)(mContext.format_context->nb_streams - 1);

mContext.codec_context = avcodec_alloc_context3(mContext.codec);

int ret;
ret = av_opt_set(mContext.codec_context->priv_data, "preset", "medium", 0);

// returns -1414549496

...


    


    I ommited error checking for brevity in the example.

    


    I tried setting preset to different values ("medium", "slow", "veryslow" etc.)
