You can download the scripts from this link: 20140807_HLStrim_JCF_v1 Procedure Hi, Please try nvv4l2h264enc and set insert-sps-pps1 idrinterval15.The setting inserts SPS/PPS in every IDR frame and sets IDR interval to a smaller value. Encode H.264/AAC video and segment it in a single command Works: Encode H.264/AAC video to MP4 Container, and in separate process, copy the bitstreams (-c copy), set the bitstream filter (-bsf:v h264mp4toannexb) and segment it using (-f segment). I have developed and tested them in a virtual Ubuntu (14.04 TLS).
To use these scripts you will need to install ffmpeg (v2.2+) and libxml2 (v20901+) (also known xmllint). To be able to do this the TS files shall be h264 baseline and they must start with an I frame (see the section: Known problems and future work).
In part 2 we’ll look at how to segment video using ffmpeg’s hls muxer. The purpose of these scripts is to perform a VERY FAST frame accuracy trimming to HLS streaming files (.TS: h264, aac), it only re-encodes the first and the last segment of whole stream. In the book I use Apple’s HTTP Live Streaming tools to do this. Since end-users have different screen sizes and different network performance, we want to create multiple renditions of the video with different resolutions and bitrates that can be switched seamlessly, this concept is called. To achieve that I developed a group of bash scripts that are able to trim a HLS stream using ffmpeg. Ffmpeg hls multiple resolutions HLS is one of the most prominent video streaming formats on desktop and mobile browsers.
Usage: ffmpeg -i infile].The main idea of this post is to practise with ffmpeg and write down my experiences, issues that I have found, possible solutions, etc. The most commonly used is x264, because it produces high quality video with a lot of settings.
