Hi , I'm trying to encode and decode audio with the
Vorbis Codec, but it is not successfull.
This is how I set the encoder:
pCodecRawCodec =
avcodec_find_encoder((AVCodecID)AV_CODEC_ID_VORBIS);
if(!pCodecRawCodec)
{
printf("codec not found\n");
return -1;
}
pCodecContextRawCodec =
avcodec_alloc_context3(pCodecRawCodec);
pCodecContextRawCodec->bit_rate =
pCodecContextRawInit->bit_rate;
pCodecContextRawCodec->sample_rate =
pCodecContextRawInit->sample_rate;
pCodecContextRawCodec->channels =
pCodecContextRawInit->channels;
pCodecContextRawCodec->sample_fmt = AV_SAMPLE_FMT_FLT;
pCodecContextRawCodec->channel_layout =
select_channel_layout(pCodecRawCodec);
if(avcodec_open2(pCodecContextRawCodec,pCodecRawCodec,NULL)<0)
{
printf("could not open codec audio\n");
}
And this is how I set the Vorbis decoder :
pCodecCodecRaw =
avcodec_find_decoder((AVCodecID)AV_CODEC_ID_VORBIS);
if(!pCodecCodecRaw)
{
printf("error found decoder \n");
return -1;
}
pCodecContextCodecRaw =
avcodec_alloc_context3(pCodecCodecRaw);
pCodecContextCodecRaw->bit_rate =
pCodecContextRawInit->bit_rate;
pCodecContextCodecRaw->sample_rate =
pCodecContextRawInit->sample_rate;
pCodecContextCodecRaw->channels =
pCodecContextRawInit->channels;
pCodecContextCodecRaw->sample_fmt = AV_SAMPLE_FMT_FLT;
pCodecContextCodecRaw->channel_layout =
select_channel_layout(pCodecRawCodec);
pCodecContextCodecRaw->extradata =
pCodecContextRawCodec->extradata;
pCodecContextCodecRaw->extradata_size =
pCodecContextRawCodec->extradata_size;
if(avcodec_open2(pCodecContextCodecRaw,pCodecCodecRaw,NULL)<0)
{
printf("could not open codec decoder vp8\n");
}
I get sometimes the error "[libvorbis @ 01e03340] packet buffer is too small"
by
encoding the raw packet. And when I think the encoding and decoding was
successfull without errors, the file has only zeros, that cant be read as raw
audio data.
There is a mistake that I make by set the AVCodecContext for Vorbis ?
Any idea would be very helpfull, thnx.
