If so, could I avoid the transcoding by command ? Or it is a necessary ?
It it is a need, WHY ? -
Quick stream from file which exists
4 mai 2017, par parsaI implement live streaming from mp4 video file which exists on the path with ffmpeg under hls format.
When my video file have the quality greater than hd720 , in encoding there are so many delays for creating .ts fragments.
I mean the .ts fragments slowly produced on my path,and because of it I have so many delays in showing the stream.
Here is my ffmpeg code for streaming :ffmpeg -re -i 123.mp4 -s cga -f hls -hls_list_size 0 -c:v libx264 -c:a aac 200p/out.m3u8
-s nhd -f hls -hls_list_size 0 -c:v libx264 -c:a aac 360p/out.m3u8
-s hd480 -f hls -hls_list_size 0 -c:v libx264 -c:a aac 480p/out.m3u8
-s hd720 -f hls -hls_list_size 0 -c:v libx264 -c:a aac 720p/out.m3u8
-s hd1080 -f hls -hls_list_size 0 -c:v libx264 -c:a aac 1080p/out.m3u8And here is the console output :
ffmpeg -re -i ../files/412-887123464/video/412-887123464.mp4 -s cga -f hls -hls_list_size 0 -c:v libx264 -c:a aac ../fil

FFMPEG to create an MPEG-DASH stream with VP8
24 avril 2017, par Kenneth WordenI’m trying to use FFMPEG to stream a live video feed from my webcam
/dev/video0. Following scattered tutorials and scarce documentation (is this a known problem for the encoding community ?) I arrived at the following bash script :#!/bin/bash
ffmpeg \
-y \
-f v4l2 \
-i /dev/video0 \
-s 640x480 \
-input_format mjpeg \
-r 24 \
-map 0:0 \
-pix_fmt yuv420p \
-codec:v libvpx \
-s 640x480 \
-threads 4 \
-b:v 50k \
-tile-columns 4 \
-frame-parallel 1 \
-keyint_min 24 -g 24 \
-f webm_chunk \
-header "stream.hdr" \
-chunk_start_index 1 \
stream_%d.chk &
sleep 2
ffmpeg \
-f webm_dash_manifest -live 1 \
-i stream.hdr \
-c copy \
-map 0 \
-f webm_dash_manifest -live 1 \
-adaptation_sets "id=0,streams=0" \
-chunk_start_index 1 \
-chunk_duration_ms 1000 \
-time_shift_buffer_depth 30000 \
-minimum_update_period 60000 \
stream_manifest.mpdWhen I run this script, my webcam light turns on, the
stream.hdrandstream_manifest.mpdfiles are written, and chunks start to be created (i.e.stream_1.chk,stream_2.chk, etc...). However, FFMPEG throws the following error :Could not write header for output file #0 (incorrect codec parameters
?) : Invalid data found when processing inputI will explain what I think I am doing with this script, and hopefully this will expose any errors in my thinking.
First, we invoke FFMPEG to use Video for Linux 2 (v4l2) to read from my webcam (
/dev/video0) of a resolution 640x480. The input format ismjpegwith a framerate of 24fps.I then declare that FFMPEG should "map" (copy) the video stream output by v4l2 to a file. I specify the pixel format (YUV420P) and use libvpx (VP8 encoding) to encode the video stream. I set the size to be 640x480, use 4 threads, set the bitrate to be 50kbps, do some magic with tile-columns and frame-parallel options, and set the I-frames to be 24 frames apart.
I then create a
stream.hdrfile. The starting index is 1. This command continues to run infinitely until I kill it, grabbing new video from my webcam and outputting it into chunks.I then sleep for 2 seconds to give the previous command time to generate a header file.
And that’s really it. The next invocation of FFMPEG simply creates the MPEG-DASH manifest file given the header generated in the previous step.
So what’s going on ? Why can I not view the video in a web browser (I’m using Dash.js) ? I serve the manifest, header, and chunks on a Node.js server so that trivial issue is not the problem.
Edit : Here is my full console output.
