I found something! It won't require an API change at all.
In AVCodecParameters there's an array member coded_side_data of type
AVPacketSideData which is defined like this:
typedef struct AVPacketSideData {
uint8_t *data;
size_t size;
enum AVPacketSideDataType type;
} AVPacketSideData;
and the enum AVPacketSideDataType has this member: AV_PKT_DATA_A53_CC
So, this would allow to add a packet to the codec parameters with
AV_PKT_DATA_A53_CC side data - as an indication for the existence of CC data.
Without any API change...
What do you think about this?
