HLS encoding support - PaulWolf - 22.05.2018 Hi, does Hybrid support HLS encoding? thank you in advance RE: HLS encoding support - Selur - 22.05.2018 Nope, Hybrid doesn't support HLS streaming since I don't know what is required for it to do so.

Thanks for your answer! I didn’t mean streaming, I meant rendering the clip to multiple resolutions and small packets of 10 seconds say.. but guess not.. RE: HLS encoding support - Selur - 23.05.2018 Looking at https://docs.peer5.com/guides/production-ready-hls-vod/ creating HLS compatible files doesn't seem complicated. From what I gathered so far the HLS options are only required during muxing, so one could encode the mp4 source file with any encoder, as long as gop size is set to X seconds, automatically adding of GOPs on scence changes is disabled and the VBV values are set. Those files could then be segmented using: ffmpeg -i sourcefile -hls_time 4 -hls_playlist_type vod -hls_segment_filename "OUTPUT FOLDER/RESOLUTIO_%03d.ts" "OUTPUT FOLDER/RESOLUTIO.m3u8 ffmpeg -i "H:\Test.mp4" -hls_time 4 -hls_playlist_type vod -hls_segment_filename "h:\hlsTest\480p_%03d.ts" "h:\hlsTest\480p.m3u8 So the values a used would need to set are: 1. the gop size in seconds, the hls package size (needs to be a multiple of the gop size in seconds value) 2. The resolutions to target (width should be enough) 3. The VBV values. After some thinking, about this I concluded, that I could add additional options to support creating a single file with segmented files and playlist, but adding an option which would tell Hybrid to create multiple resolution etc. in one go conflicts with too much of the inner workings of Hybrid. Writing a small gui for the script from https://docs.peer5.com/guides/production-ready-hls-vod/ that works on Windows/Mac/Linux wouldn't be complicated either, but that would not be Hybrid but another tool.

RE: HLS encoding support - Selur - 23.05.2018 Nothing to thank for, haven't done anything so far. Cu Selur RE: HLS encoding support - Selur - 23.05.2018 What OS do you use? I uploaded a 64bit Windows build of 'KissHLS' to my GoogleDrive. Assuming you use Windows: Download the file, extract it, start KissHLS and test it. I basically does what the script from https://docs.peer5.com/guides/production-ready-hls-vod/ suggested with some minor adjustments to the ffmpeg call. Cu Selur |
