Nginx VOD Transcoding
21 décembre 2015, par nicb19I’m trying to setup MPEG-DASH video on demand streaming using nginx. I came across the nginx vod module which works great with dash.js but am wondering if anyone has managed to get real-time transcoding working.
I’ve currently got it setup to play H264 MP4 local files, producing a MPD manifest for a single MP4. I know I can transcode multiple versions of the video and store them on the server, creating a multi URL manifest, but I only have limited space on the server so am not able to do this. Instead, I’m trying to find a way to transcode in real-time to allow more adaptive bitrate streaming like is possible with the nginx rtmp module and ffmpeg (however with MPEG-DASH instead of RTMP since I don’t want to use flash).
Does anyone know of a way to do this ? Thanks in advanced.

ffmpeg converting m4s to mp4
12 mai 2022, par programming freakI'm working on DASH, trying to optimize QoE for the end user.



I had a video and encoded it using ffmpeg into different bitrates and everything is fine, and the video is playable using dash.



What I want is to combine the received segments from the users into one m4s and convert that m4s to mp4.



I tried a lot of ways in ffmpeg, but it always give me this error :



[mov,mp4,m4a,3gp,3g2,mj2 @ 0x9a9e500] could not find corresponding track id 1
[mov,mp4,m4a,3gp,3g2,mj2 @ 0x9a9e500] could not find corresponding trex
[mov,mp4,m4a,3gp,3g2,mj2 @ 0x9a9e500] error reading header
test2.m4s: Invalid data found when processing input




segment_1.m4s is there.



How can I resolve this issue ?
