1. We will stream H264/AAC at same time and get those frames from ring buffer(share memory). 2. At H264 sub session with 30fps, that mean H264 task will call doGetNextFrame() 30 times per sec. Each time, our code will make sure doGetNextFrame() get one H264 frame(I or P) to deliver to fTo.

Each time, our code will make sure doGetNextFrame() get one H264 frame(I or P) to deliver to fTo. So, doGetNextFrame() may be blocking by ring buffer. 3. At AAC sub session, we would not drop any frames, but it may also be blocked. $ ffprobe -i input.ts -show_frames -select_streams v:0 -print_format flat | grep pkt_pts= frames.frame.435.pkt_pts=4205067450 frames.frame.436.pkt_pts=4205071050 And I need to find out the pkt_pts timestamp on the extracted files possibly with only one command. Hi, Zachary I've successfully called Intel Quick Sync H.264 Encoder and ICodecAPI, and I can dynamicly change video resolution, frame rate, profile.

I want to intercept every frame of an h.264 30 fps stream (not variable rate, life is good) and get its frame number and timestamp. So as I understand the doc, that should be in the GstBuf.dts and GstBuf.offset fields. I was going down the pad probe route but found that the identity plugin as per the doc a much easier and better route: For example, if last real frame has timestamp 27.5 sec, I record this frame with timestamps 28.5 sec, 29.5 sec, 29.966 sec.

With this change, we start using WebRTC given timestamp() so that OveruseFrameDetector can match the timestamps and calculate the stats.

BUG=597087 TEST=googAvgEncodeMs and googEncodeUsagePercent works on Mac(H264) and veyron_jerry(VP8). 2016-02-22 This memo describes an RTP Payload format for the ITU-T Recommendation H.264 video codec and the technically identical ISO/IEC International Standard 14496-10 video codec. The RTP payload format allows for packetization of one or more Network Abstraction Layer Units (NALUs), produced by an H.264 video encoder, in each RTP payload.

These will typically contain timing information, specifically "time_scale" and "num_units_in_tick". In most scenarios the frame rate is fixed which is specified by "fixed_frame_rate_flag" in the SPS. Okay, so in the H264 P-Frame section I will comment out the assignment of lastTimestamp (lastTimestamp = h264pFrame.Timestamp).
