| int64_t AVPacket::convergence_duration |
Time difference in stream time base units from the pts of this packet to the point at which the output from the decoder has converged independent from the availability of previous frames.
That is, the frames are virtually identical no matter if decoding started from the very first frame or from this keyframe. Is AV_NOPTS_VALUE if unknown. This field is not the display duration of the current packet.
The purpose of this field is to allow seeking in streams that have no keyframes in the conventional sense. It corresponds to the recovery point SEI in H.264 and match_time_delta in NUT. It is also essential for some types of subtitle streams to ensure that all subtitles are correctly displayed after seeking.

Presentation timestamp in time_base units; the time at which the decompressed packet will be presented to the user.
Can be AV_NOPTS_VALUE if it is not stored in the file. pts MUST be larger or equal to dts as presentation cannot happen before decompression, unless one wants to view hex dumps. Some formats misuse the terms dts and pts/cts to mean something different. Such timestamps must be converted to true pts/dts before they are stored in AVPacket.
