ffmpeg - How to determine if -movflags faststart is enabled ? PHP

6 juillet 2017, par IIIOXIII

While I am able to encode an mp4 file which I can play on my local windows machine, I am having trouble encoding files to mp4 which are readable when streaming by safari, etc.

After a bit of reading, I believe my issue is that I must move the metadata from the end of the file to the beginning in order for the converted mp4 files to be streamable.

To that end, I am trying to find out if the build of ffmpeg that I am currently using is able to use the -movflags faststart option through php - as my current outputted mp4 files are not working when streamed online.

This is the way I am now echoing the -help, -formats, -codecs, but I am not seeing anything about -movflags faststart in any of the lists :

exec($ffmpegPath." -help", $codecArr);

for($ii=0;$iibr>';

}

Is there a similar method of determining if -movflags fastart is available to my ffmpeg build ? Any other way ? Should it be listed with any of the previously suggested commands ? -help/-formats ?

Can someone that knows it is enabled in their version of ffmpeg check to see if it is listed under -help or -formats, etc.?

TIA.

ffmpeg doesn't generate video from images

6 juillet 2017, par mans

I am trying to create a video from jpeg images using ffmpeg. The generated video should be in x264 or x265 format.

I have a directory with 36 images . Each image size is around 60Mpixel. They are names as follow :

frame00000.jpg
frame00001.jps
frame00002.jpg
....
frame00035.jpg

I read documentation and several posts in SO and I came to write a batch file to call ffmpeg as follow :

 ffmpeg.exe -r 1/5 -start_number 0 -i %1\frame%%05d.jpg -c:v libx264 -vf "fps=1,format=yuv420p" out1.mp4

when I run this command, I am getting this output from the ffmpeg, which is strange :

C:\Users\m\Desktop\ffmpeg-20170702-c885356-win64-static\bin>ffmpeg.exe -r 1/5 -start_number 0 -i "C:\Resized"\frame%05d.jpg -c:v libx264 -vf "fps=1,format=yuv420p" out1.mp4

As can be seen :

it reported :

deprecated pixel format used, make sure you did set range correctly

what that means ?

It is trying to process more than 36 frames, when we only have 36 frames.
Until frame 25, size is zero and bitrate is N/A and after frame 25, size became none zero.
It runs for several hundred images and then stops, but I can not play video.
After frame 47, FPS became zero.
I can not play back the output video.

How can I fix these problems and create a video from these frames ?

Edit1

After getting some reply, I noted that h264 can not support the final resolution so I converted to use VP9 and I am using this command :

ffmpeg -i %1\frame%%05d.jpg -c:v libvpx-vp9 -b:v 2M -c:a libvorbis output.webm

I am getting the right number of frames, but I can not play the output using VLC.

Is there any player that can play this resolution ?
Is there any way that I can check that the data in video is correct other than playing it ? For example by extracting them into several images and view the images.

ADD Image overlay to ffmpeg video stream

1er juillet 2017, par Chris

I am new to ffmpeg and want to add an HUD to the video stream, so a few questions.

What file do I need to edit.
What do I need to do to achieve this.

Thanks in advance. Also I am VERY new to all of this, I will need instructions step by step

I saw other questions saying to add this : ffmpeg -n -i video.mp4 -i logo.png -filter_complex "[0:v]setsar=sar=1[v];[v][1]blend=all_mode='overlay':all_opacity=0.7" -movflags +faststart tmb/video.mp4

But I dont know where to put it, i entered it in the terminal and got this :

pi@raspberrypi:~ $ ffmpeg -n -i video.mp4 -i logo.png -filter_complex "[0:v]setsar=sar=1[v];[v][1]blend=all_mode='overlay':all_opacity=0.7" -movflags +faststart tmb/video.mp4
