This may result in incorrect timestamps in the output file. GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together. Ease of use would be 10 if a batch mode would be added to UI. What I believe is that the encoder is not sending the PPS NAL unit more than once (when the stream is first started) so when a client attempts to connect after the server is started, that information isn't there. Anyone know why this is happening and what are some decent alternatives to convert MKV to TS?. dll FFmpeg codec library version 56. c++ - Problem to Decode H264 video over RTP with ffmpeg (libavcodec) I set profile_idc, level_idc, extradata et extradata_size of AvCodecContext with the profile-level-id et sprop-parameter-set of the SDP.

The output of the encoder is an H. The Video Decode and Presentation API for Unix (VDPAU) provides a complete solution for decoding, post-processing, compositing, and displaying compressed or uncompressed video streams. I want to segment any stream to hls using the gstreamer and python, if stream already is hls just copying and being able to select.

I haven't changed any settings, so I'm fairly confident this is an issue with the program itself. 研究了一下,一种方法是采用ffmpeg库,可以先将H264文件解码,再编码生成MP4文件,但这种方式效率较低,10M的视频可能需要几秒钟才能完成。 另一种方式根据MP4文件协议直接将H264包封装成MP4格式,由于是直接基于MP4的封装,因而效率很高。. py What's wrong?

Initial stream identification and final stream statistics. What does it mean “invalid NAL unit size” for h. 264 with error detection, recovery, and concealment including two parsing functions for efficient detection of errors in exp-Golomb codewords, recovery.
