This build fixes one problem with old Intel CPUs (like 2700 or older) - wrong timestamps on encoded frames if you use H.264 Intel QuickSync encoder.

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.

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. But when it comes to change bit rate, the .264 bitstream illustrates that the configure doesn't work.

H264 frame timestamp

Hi, Zachary I've successfully called Intel Quick Sync H.264 Encoder and ICodecAPI, and I can dynamicly change video resolution, frame rate, profile. But when it comes to change bit rate, the .264 bitstream illustrates that the configure doesn't work. Hello, I am trying to stream H264 with an RTSP server using Gstreamer. The H264 is encoded with v4l2h264enc.

This may result in incorrect timestamps in the output file. frame= 660 fps=0.0 [lavf] stream 0: video (h264), -vid 0 [lavf] stream 1: audio (aac), -aid 0, -alang und

2. H.264 frame timestamps with MP4 file pts When using the UMC classes for H.264 decoding, there does not seem to be a way to correlate the timestamps of the input data (coming from a parsed MP4 file in this case) with the timestamps of the frames produced by calls to theGetFrame method. 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). H 264 Encoder H.264 NAL "stream" Presentation timestamp based on gPTP time that talker receives each NAL unit.

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. For h264/aac sync, I use testProgs/testOnDemandRTSPServer.cpp to do: 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.

Hello, I am trying to stream H264 with an RTSP server using Gstreamer. The H264 is encoded with v4l2h264enc.

Those streams don't have B-frames and there is no need for delaying. It would be nice if we could configure Ffmpeg H264 decoder context to signal the streams have no B frames (sps->num_reorder_frames = 0).
