get UTC time of every video frame using ffmepg
22 septembre 2015, par MathxH ChenI just read a RTSP stream from my IP Camera using FFMPEG. I need to display UTC time of every frame and video frame synchronously. The player GUI I created by Qt.
At very first, I just use libVLC to implement my requirement. Then, I just found out that LibVLC cannot get UTC timestamp of every frame(https://forum.videolan.org/viewtopic.php?f=4&t=128403), So I was out to move from libvlc to ffmepg. I code a Demo read RTSP using ffmpeg library and print the presentation time of every frame . but I find the presentation time is relative , It start from zero up to end. How I can convert the time to UTC ? RTP Packet’s timestamp is relative, It only need RTCP sender report’s absolute timestamp to calculate the UTC. How can I get the UTC time of every frame using FFMPEG ??
In FFPMEG every frame has own pts in struct AVFrame, the pts just copied from AVPacket, the struct AVStream has time_base this field, UTC time is equal to time_base*pts ?
my code snippet as follows :
//SDL End----------------------
while(av_read_frame(pFormatCtx, packet)>=0){
if(packet->stream_index==videoindex){
ret = avcodec_decode_video2(pCodecCtx, pFrame, &got_picture, packet);
if(ret < 0){
printf("Decode Error.\n");
return -1;
}
int64_t utc = packet->pts * av_q2d(pStream->time_base);
printf("UTC is :%I64d\n", utc);What’s Wrong ?

How to play video at exact seek time ?
3 mai 2016, par RanceAI was working on a video player of an app and I ran into a problem.
I need a video’s playing cycle locked into a specified time interval. For instance, I need a video loop to play from
00:04
to00:08
.My dilemma is, the video only has keyframes at
00:00
and00:10
,MediaPlayer.seekTo(4000)
will seek the start time to00:10
which is not what I expected. I need the video to play at a precise time,00:04
to00:08
, not00:00
to00:10
.FFPlay
also supportsAVSEEK_FLAG
, but none of the flags seem to work in my case.Maybe playing at
00:00
then fast-forward encoding to00:04
is a good idea, but I have no idea how to implement that. MyFFMPEG
experience is poor.Any help would be greatly appreciated.
