read_packet()

Read data from the file buffer into the avio context buffer.

ReadNextSubtitle()

int TextSubtitleParser::ReadNextSubtitle

(

void

)

Read the next subtitle in the AV stream.

av_read_frame guarantees that pkt->pts, pkt->dts and pkt->duration are always set to correct values in AVStream.time_base units (and guessed if the format cannot provide them). pkt->pts can be AV_NOPTS_VALUE if the video format has B-frames, so it is better to rely on pkt->dts if you do not decompress the payload.
