Seeking works like for a local file.
int64_t avio_size(AVIOContext *s)
Get the filesize.
int avio_feof(AVIOContext *s)
Similar to feof() but also returns nonzero on read errors.
static av_always_inline int64_t avio_tell(AVIOContext *s)
ftell() equivalent for AVIOContext.

int av_get_audio_frame_duration2(AVCodecParameters *par, int frame_bytes)
This function is the same as av_get_audio_frame_duration(), except it works with AVCodecParameters in...
#define AV_PKT_FLAG_CORRUPT
The packet content is corrupted.
AVStream * avformat_new_stream(AVFormatContext *s, const AVCodec *c)
Add a new stream to a media file.
#define AVERROR_EOF
End of file.
int64_t av_rescale_rnd(int64_t a, int64_t b, int64_t c, enum AVRounding rnd)

Return NULL if CONFIG_SMALL is true, otherwise the argument without modification.
uint64_t channel_layout
Audio only.
enum AVMediaType codec_type
General type of the encoded data.

Audio only.
This structure stores compressed data.
int flags
A combination of AV_PKT_FLAG values.
This structure contains the data a format has to probe a file.
