H264 header come off VC with 0 timestamps, which means they get a strange timestamp when processed with VC/kernel start times, particularly if used with the inline header option. Remember the last frame timestamp and use that if set, or otherwise use the kernel start time.

I have an issue with H264 output frames PTS. The input is a packets with PTS and DTS. In case PTS and/or DTS is available, I set the TimeStamp and DecodeTimeStamp values. But the output packets are not in the PTS increasing order. For example: 40, 80, 120, 160, 320, 240, 360, 280(milliseconds).

For example, my application uses a native time base that is in microseconds (thus if you have a frame rate of 15, the timestamp of each frame is increased by 1000000/15 = (about) 66667). This can be calculated to the stream's time_base with the av_rescale_q function, in the following t: copy timestamp to clipboard. left: step 1 frame left. right: step 1 frame right. space: toggle play/pause. home: go to first frame. end: go to last frame.

I have an issue with H264 output frames PTS. The input is a packets with PTS and DTS. In case PTS and/or DTS is available, I set the TimeStamp and DecodeTimeStamp values. But the output packets are not in the PTS increasing order.

The H264 encoder does not generate B-frame, then the RTP timestamp should be the PTS + random offset (the same for all streaming session) If the encoder generate B-frames (or B-slices), then the decoding order needs to be modified, since B-frame requires the next frame to be decoded, so it must be sent before. Timestamp issue with the h264 encoder & decoder I wrote a GStreamer plugin to decode h264 data with intel media SDK.mfxBitstream.TimeStamp is passed for each frame, but the output timestamps frommfxFrameSurface1.Data.TimeStamp are not in the increasing order.MFXVideoDECODE_DecodeFrameAsync is used to decoder h264 frames. ffmpeg -y -i "123.avi" -c:v h264_nvenc -r 1 -g 1 -vsync vfr "temp.avi" The timestamp of the 1st frame is delayed according to -r (by 1/r exactly), while the rest of the timestamps remain unchanged (have verified this with more complex input source).

I think the final solution should be prepending SPS/PPS to all I-frames and pack that in one 'encoded image'.

I use live555 to do rtsp server from my h264/aac live stream. First, I know every frame about timestamp and frame len from two linux fifo. And I use ByteStreamFileSource.cpp and ADTSAudioFileSource.cpp to get the frame data.

Aggregate all NAL units with the same timestamp (adds one frame of latency) The results of the search are gst_h264_parse_subset_sps GstH264ParserResult gst_h264_parse_subset_sps (GstH264NalUnit * nalu, GstH264SPS * sps). Parses data, and fills in the sps structure.. This function fully parses data and allocates all the necessary data structures needed for MVC extensions. The resulting sps structure shall be deallocated with gst_h264_sps_clear when it is no longer needed.
