Hi, the problem I want to describe is similar to "Generate individual HLS-compatible .ts segments on-demand by downloading as little bytes as possible from a remote input file" described here http://ffmpeg.org/pipermail/ffmpeg-user/2016-December/034513.html - unfortunately no answers there. Initial assumptions are: - need to provide streaming solution based on HLS-compatible MPEGTS segments - for now need to stream audio only (maybe audio+video in the future, so generic solution would be the best for me) - my data source is a group of WAV file segments, exactly 10 seconds each - if you take all WAV segments and concatenate them you will get a nice, seamless audio track (no glitches, gaps etc.) - the cost of retrieving each WAV segment from my storage is relatively high My approach: - create m3u8 index file before any segments are actually available, as I know how many segments I need to generate and I also know their duration - when a MPEGTS segment is requested, collect WAV data from storage and generate MPEGTS file using FFmpeg: For first segment: ffmpeg -i input_1.wav -acodec aac -output_ts_offset 0ms output_1.ts For second segment: ffmpeg -i input_2.wav -acodec aac -output_ts_offset 10000ms output_2.ts etc... My problem: - generated segments are not exactly 10 seconds long - gaps can be heard between some audio segments (may this be caused by above issue?) Any ideas how to generate single MPEGTS segments that will not cause glitches during playback? I need to expose the data through web API written in ASP.NET C#. Any idea on how to solve this problem, even if it may not use FFmpeg at all, would be appreciated. Thanks, Jan
