20 Oct 2014 The decoding timestamp (DTS) denotes the time when the frame3 H.264 is a successor of H.2632 and provides a better quality at the same.

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). 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. 2013-09-09 · But when I use it to play the streaming raw H264 frames, sometimes it's perfect to play for several hours, but sometimes the render frames are broken or hanging in just several seconds. The SampleRequested events still occur, but the frame can't be displayed on media element correctly. I talked this over with the H264 encoder folks and this is because Main profile enables B frames, and when there are B frames the encoder makes timestamp adjustments to ensure that PTS (presentation time stamp) >= DTS (decode time stamp). "timestamp": 1009923925 I'm doing a fixed 30fps.

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.

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.

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. This tool extracts frames, motion vectors, frame types and timestamps from H.264 and MPEG-4 Part 2 encoded videos. This class is a replacement for OpenCV's VideoCapture and can be used to read and decode video frames from a H.264 or MPEG-4 Part 2 encoded video stream/file.
