int skip_samples
Number of samples to skip at the start of the frame decoded from the next packet.
struct AVStreamInternal::@260 * info
Stream information used internally by avformat_find_stream_info()
int reorder
Set to 1 if the codec allows reordering, so pts can be different from dts.
int skip_to_keyframe
Indicates that everything up to the next keyframe should be discarded.
AVCodecContext * avctx
The codec context used by avformat_find_stream_info, the parser, etc.

int bitstream_checked
Whether or not check_bitstream should still be run on each packet.
uint8_t pts_reorder_error_count[MAX_REORDER_DELAY+1]
