Hey there,
I’m trying to encode a sequence of images into Pro Res 422 in the MOV container.
I already had a look at the example: muxing.c and it looks promising.
However, I can’t figure out how to tell the encoder to use ProRes instead of
H.264 for MOV.
Here’s what I’ve tried (mostly unaltered sample …):
AVOutputFormat* pOutputFmt;
AVFormatContext* pFormatCtx;
AVStream* pVideoStream;
AVCodec* pVideoCodec;
/* Initialize libavcodec, and register all codecs and formats. */
av_register_all();
/* allocate the output media context */
avformat_alloc_output_context2(&pFormatCtx, NULL, "mov", filename.c_str());
Try after that:
pOutputFmt = pFormatCtx->oformat;
pOutputFmt->video_codec = AV_CODEC_ID_PRORES;
(add stream and open codec here).
Ok, got it. That works perfectly.
And how would I go about defining the different Pro Res flavors? Like
Proxy/LT/Standard/HQ?
My guess is that you need to modify the AVCodecContext* or pass some
opts with set_opts. You will need to read the source code of prores I
am afraid.
