Hi to all
I found that ffmpeg can decode PRORES, while it seems that avcodec doesn't.
If I issue:
ffmpeg.exe -i test_prores.mov test.mp4
it convert the mov prores file correctly, whilst using libavcodec
doesn't. Here is the snippet of code:
vd_codec = avcodec_find_decoder(AV_CODEC_ID_PRORES);
pCodecCtxFF = avcodec_alloc_context3(vd_codec);
glob_frm = av_frame_alloc(); // allocate and init a re-usable frame
avcodec_open2(pCodecCtxFF, vd_codec,NULL);
av_init_packet(&thpkt);
// Read a single PRORES FRAME and put it into tempBuff
fileSize = PutFileIntoBuffer(srcFile.c_str(),tempBuff);
thpkt.size = fileSize; thpkt.data = tempBuff;
conv_res = avcodec_send_packet(pCodecCtxFF, &thpkt);
if(conv_res<0)
{
if(av_strerror(conv_res, errbuf, 512)==0) stre.printf("Error
sending packet : %s",errbuf);
else stre.printf("Error %x returned from avcodec_send_packet :
%s",errbuf);
goto __exit_pres;
}
result is the message "Error sending packet : Not yet implemented in
FFmpeg, patches welcome".
I attempt to compile with and without --enable-version3 in the configure
but nothing changes.
Anyone experienced decoding of PRORES frame ?
Regards
