Encoded mp4 video won't play in Firefox v33
3 novembre 2014, par Michael HeubergerWhen this video is encoded with the following ffmpeg command, it cannot be played in Firefox v33 (a blank screen appears). But when I play it in the native VLC player, it works. So here the long ffmpeg command :
$ ffmpeg -r 15 -f image2 -i /home/(...)/frames/%d.jpg -i
/home/(...)/preview.wav -y -acodec libfdk_aac -b:a 128k
-vcodec libx264 -b:v 386k -preset ultrafast -profile:v baseline
-crf 6 -pix_fmt yuv420p -loglevel warning -movflags faststart
/home/(...)/preview.mp4As you can see, preview.mp4 is encoded by a sequence of jpg images with a given wav file.
The ffmpeg output is just this
[wav @ 0x35ff460] Estimating duration from bitrate, this may be inaccurate
Guessed Channel Layout for Input Stream #1.0 : mono
[swscaler @ 0x35f0d80] deprecated pixel format used, make sure you did set range correctlyAny clues why it won’t play on Firefox (and what the other ffpmeg warnings mean) ?
Thanks !!!

Node-Fluent-ffmpeg stops with Error initializing complex filters. Invalid argument
28 août 2020, par V.PanichkinI use node-fluent-ffmpeg to generate ffmpeg command. I created a node.js app, but it throws an exception :


Error: ffmpeg exited with code 1: Error initializing complex filters.
Invalid argument

 at ChildProcess.<anonymous> (/home/victor/Documents/work/recorder_ws/node_modules/fluent-ffmpeg/lib/processor.js:182:22)
 at ChildProcess.emit (events.js:315:20)
 at Process.ChildProcess._handle.onexit (internal/child_process.js:275:12)
</anonymous>


The command that was generated by Node-Fluent-Ffmpeg is


ffmpeg -i /home/user/videos/1.webm -i /home/user/videos/3.webm -i /home/user/videos/4.webm -i /home/user/videos/5.webm -y -filter_complex "[0:v] scale=qvga [a0];[1:v] scale=qvga [a1];[2:v] scale=qvga [a2];[3:v] scale=qvga [a3];[a0][a1][a2][a3]xstack=inputs=4:layout=0_0|w0_0|0_h0|w0_h0[out]" -map "[out]" -c:v libx264 -t '30' ./server-generated.mkv



I checked it several times and didn't find any problem. Afterwards, I run this generated command directly in the console and it works fine.


Could someone tell me why node-fluent-ffmpeg cannot run this command with a valid ffmpeg command and throws invalid argument exception ?
