int64_t avio_seek(AVIOContext *s, int64_t offset, int whence)
fseek() equivalent for AVIOContext.
unsigned int avio_rb16(AVIOContext *s)
int avio_feof(AVIOContext *s)
Similar to feof() but also returns nonzero on read errors.

ftell() equivalent for AVIOContext.

#define AV_PKT_FLAG_CORRUPT
The packet content is corrupted.
void av_shrink_packet(AVPacket *pkt, int size)
Reduce packet size, correctly zeroing padding.
AVStream * avformat_new_stream(AVFormatContext *s, const AVCodec *c)
Add a new stream to a media file.
#define AVERROR_INVALIDDATA
Invalid data found when processing input.
#define AVERROR_EOF
End of file.
#define AV_LOG_ERROR
Something went wrong and cannot losslessly be recovered.
common internal API header
#define NULL_IF_CONFIG_SMALL(x)
Return NULL if CONFIG_SMALL is true, otherwise the argument without modification.
This struct describes the properties of an encoded stream.
int extradata_size
Size of the extradata content in bytes.
int64_t bit_rate
The average bitrate of the encoded data (in bits per second).
enum AVMediaType codec_type
General type of the encoded data.
uint8_t * extradata
Extra binary data needed for initializing the decoder, codec-dependent.
enum AVCodecID codec_id
Specific type of the encoded data (the codec used).
int sample_rate
Audio only.
This structure stores compressed data.
int flags
A combination of AV_PKT_FLAG values.
int64_t duration
Duration of this packet in AVStream->time_base units, 0 if unknown.

Presentation timestamp in AVStream->time_base units; the time at which the decompressed packet will b...
int64_t pos
byte position in stream, -1 if unknown
This structure contains the data a format has to probe a file.
int buf_size
Size of buf except extra allocated bytes.
unsigned char * buf
Buffer must have AVPROBE_PADDING_SIZE of extra allocated bytes filled with zero.
