I used 'av_read_frame'; To my information, it's not deprecated.
Have no idea how to read/write in ffmpeg without those functioms.
You can customize your io, using 'init_put_byte' to set your custom io
routine instead of default callback, here's outline
struct NALMsg {
uint8_t* data;
int size;
char header;
NalMsg* next;
}
int my_read(void* opaq, uint8_t* buf, int size)
{
NalMsg msg;
... parse buffer 'buf' into list of NAL units in NALMsg
return size;
}
main()
{
...
ByteIOContext ByteIOCtx;
init_put_byte(&ByteIOCtx, pDataBuffer, lSize, 0, this, &my_read, NULL, NULL);
...
}
av_read_frame will call your 'my_read' function to "do your thing"
Let me know if you find other methods.
