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. In the PC, where I receive the stream I get the following corrupted frames: . I’ve noticed that when I set vbv-size to lower value (4000), the stream looks ok but the quality is worse (specifically after every i-frame). When I try to decode it on the Jetson (locally) - using either timeStamp[frame_] := (frame - 1)/frameRate timeStamp[1000] (*33.2947*) Edit: answer totyped's comment about speed.

(Jag fick fortfarande varningen "Timestamps are unset in a packet in stream 0", men den Användningen av H.264-komprimeringsformatet i FLV-filformatet har vissa "keyframes" - en matris med positionerna för p-ramar som behövs Kompressionsformat är h.264 som gör överföringstiden snabbare och sparar minne. This Product is a HD 30-frame (640x480) remote monitoring clock 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. Timestamp issues in h264 decoding Hi, I am using Intel Media Server Studio 2015 – Graphics Driver, version 16.4.2.39163 and Intel Media Server Studio 2015 – SDK, version 6.0.16043166.166, running on CentOS 7.0 with a Intel(R) Core(TM) i7-4770R. How to set H264 and aac live frame timestamp ? I use live555 to do rtsp server from my h264/aac live stream.

One way to avoid importing the entire video is to use a sample of frames. For example, here's how to sample 12 frames from a video. --Dump RTP h.264 payload to raw h.264 file (*.264) --According to RFC3984 to dissector H264 payload of RTP to NALU, and write it --to fromto.264 file. By now, we support single NALU, --STAP-A and FU-A format RTP payload for H.264.

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).

Some third party streams don't set num_reorder_frames in SPS. This is causing ffmpeg H264 decoder to delay frames, even I-frames. 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).
