  • 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.)

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.

    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.
