FFMPEG to create an MPEG-DASH stream with VP8
16 septembre 2019, par Kenny 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.

AR.Drone 2, ffmpeg avcodec_decode_video2( ) segmentation fault
21 avril 2014, par mechanicalmanbI have been trying to decode the video stream from an AR.Drone 2.0 (http://ardrone2.parrot.com/) for a while now with no success. Despite several examples that I have been following closely (I’d paste links, but I am not allowed) I cannot escape a segmentation fault inside of the ffmpeg libavcodec library. I thought that perhaps I was making some kind of mistake in the multi-threaded structure I was building, so I cut out everything except the bare minimum you need to connect to the drone, collect a frame from the drone, and send it to ffmpeg’s avcodec_decode_video2() function.
I compiled the ffmpeg source (I’ve actually tried three different releases !) and can get the ffplay utility to display the drone’s video TCP stream. The video lags significantly, but at least I know the drone isn’t sending me complete gibberish.
Has anyone encountered a problem like this before ? What could be causing this segmentation fault, and what can I do about it ? Is there a way to isolate a test on ffmpeg so that I can be sure it is the library and not something I’ve been doing this entire time ?
Thanks for your time.

Could not find tag for codec h264 in stream #0 (mp4)
18 août 2019, par TabsNotSpacesI’ve been using the sickbeard_mp4_converter for a while to convert video files to mp4 by generating a script for ffmpeg. I’m not sure what I changed, but the ffmpeg script it generates no longer works and I’m having trouble debugging it. Can anyone tell from my log what the issue is ? Yes, its supposed to be an mp4 to an mp4, which is typically fine.
I’m at the point where I’m using an mp4 that worked with the same autogenerated script yesterday but it no longer is. I remember updating ffmpeg but downgrading did not resolve the issue, though I may have not downgraded enough.
