Dear group, I am trying to write a code to encode (in realtime) a stream with audio and video in Linux environment. -The video source is read with av_read_frame and the /dev/videoX is opened. The pts values with respect to the first packed seem to be reasonable. -The audio source comes from alsa: here I see really strange behaviour. The pts value of the second packet with respect to the first pts packet seems to be "delayed" from 0.4s to 1.8s. I don't understand this behaviour: I checked the time from start to the second packet and the elapsed time cannot be justified (ms and not s). -Finally, when I write audio and video in the output MP4 stream (I use libx264 and libfdk_aac for video and audio respectively) the audio stream is delayed.
I don't know what to check. Please give me suggestions to solve this issue. What can I check? Thanks in advance and best regards.
