crystalhd : Fix up the missing first sample
15 octobre 2016, par Philip Langdalecrystalhd : 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

C++ : Encoding H264 with FFmpeg, unable to set preset
3 janvier 2023, par Mateusz WójtI'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.)
