Hi There

I am trying to understand the pts value in an audio encoded packet in ffmpeg.

I checked my timebase to be 1/44100

and some pts values : 70754080000, 70759090000, back to back packet pts values.

I dont know how to convert that to real time. I would imagine it having something to do with the time base.

I an se that the packets seem to be coming in every half a second, but not sure how that equates to the numbers provided.

Any help would be greatly appreciated.

read the avformat.h there stands:

/* AVPacket.pts, AVPacket.dts and AVPacket.duration timing information will be
 * set if known. They may also be unset (i.e. AV_NOPTS_VALUE for
 * pts/dts, 0 for duration) if the stream does not provide them. The timing
 * information will be in AVStream.time_base units, i.e. it has to be
 * multiplied by the timebase to convert them to seconds.*/

it are timestamps from the stream.
