How to find the presentation time stamp of a given frame number for FFMPEG decoding ?
21 août 2017, par Deepankar AryaI am using the C APIs of ffmpeg for some video processing. My aim is to extract the screen shot of a given frame number. I have understood that ffmpeg has an av_seek_frame function to seek to a given timestamp(expressed in appropriated base units of the video stream). I assume that I will have to goto to the most recent I frame for the given frame(using the AVSEEK_FLAG_BACKWARD flag) and read onwards untill I meet the required frame. For that I need to give a seek time stamp to the av_seek_frame function. My main issue is that given a frame number, how do I find an associated presentation time stamp to seek to ?

avformat/mpegts : respect program number when merging streams
9 juillet 2019, par Marton Balintavformat/mpegts : respect program number when merging streams
merge_pmt_versions was not usable if multiple programs were present because
when it was searching for candidate streams it did not make sure that the PMT was
of the same program. This caused the streams of all programs to get merged into
a single (garbled) program.This patch makes sure that the program number (service ID) is also matching
with the old streams when parsing the PMT making the feature useful for multi
program streams.This change might cause issues for single program streams if the program number
changes, but I think it is acceptable because the goal of the option is to make
the parsing resilient to PID changes, and that is still working as expected.Signed-off-by : Marton Balint <cus@passwd.hu>
