mp3 + image to flv 2

ThomasJSmart · Sep 25, 2007

Hi,

Im looking for a commandprompt method to convert 1 mp3 file and 1 or more image files into a single flv file...

i use mencoder to convert most video files to flv...

this does not work for mp3 tho, so i guess the steps would be:

convert the 1 or more images to a video
add the mp3 as audio to this file
convert the whole thing to flv

having some problems finding the right software and methods tho.

can anyone help me?

thanks!

...and this has what exactly to do with Linux servers?

Anyway, from the top of my head, have your files named sequentially. i.e. img00000.png, img000001.png ... etc. Get ffmpeg. Use: ffmpeg -r 1 -i img%05d.png -i some_music.mp3 -y -f flv -r 5 -s 352x240 some_output.flv. The first -r denotes the rate at which the image files are read in (fps). A value of 1 plays 1 image every 1 second, 0.5 plays 1 image every 2 seconds etc. Adjust to fit audio.

Thank you, i will try this.

this has to do with linux server because it is running on a linux server, the files to be converted will be uploaded, and the command will be called from php's exec or system

ThomasJSmart · Sep 26, 2007

Iv been trying this out however it seems the image is added to the file but the audio is not. any idea's?

exec("/usr/local/bin/ffmpeg -r 1 -i audiofile.mp3 -i image.png -y -f flv -r 0.1 -s 444x250 output.flv");

i tried the code in the command prompt with just audio and got this:

zeland · Sep 26, 2007

I think you've got the inputs wrong. The frame rate option -r, must come before the image input and not the audio input. Also, you should have the second -r = 1. From you command example, the resulting video would only play for 1/10 of a second for every input frame.

ThomasJSmart · Sep 26, 2007

ok, changed it to:

/usr/local/bin/ffmpeg -i audio.mp3 -r 1 -i image.png -y -f flv -r 1 -s 444x250 output.flv

but still the same result, 1 frame video with no audio.

zeland · Sep 26, 2007

OK. I messed around a bit and found this to work better.

Code:

ffmpeg -loop_input -t 30 -i image.png -i audiowav.mp3 -y -f flv -r 1 -s 352x240 test.flv

In this example, my audio is 30 seconds long. So i ask ffmpeg to loop my input image (-loop_input) for 30 seconds (-t 30).

I'm going to ask a tangent question, don't want to sidetrack the OP's thread...

If one wanted to make a slideshow with, say, 10 images over 2 minutes, would this solution still be appropriate? How?

zeland · Sep 26, 2007

Have your images named in sequential order. i.e. pic0001.png pic0002.png ... pic0010.png. 10 images over 120s = 12s/image = 1/12 fps.

As per my initial command:

Code:

ffmpeg -r 1:12 -i pic%04d.png -i some_music.mp3 -y -f flv -r 1 -s 352x240 some_output.flv

For me however, the first image always plays too fast (plays only for 1 second). Don't know why yet. May inquire over at the ffmpeg user forum.

thedaver · Sep 26, 2007

COOL!

zeland, that nomenclature is new to me

Code:

ffmpeg -r 1:12 -i pic%04d.png

"%04d" looks like string formatting speak, but is that usage specific to a particular shell or is that something that ffmpeg has as a unique parameter parsing capability?

zeland · Sep 26, 2007

Yup, %04d is formating placeholder just like what is used in C /PHP programing printf() function. I've used this nomenclature for as long as I've used ffmpeg. Other video editing application like MJPEG Tools png2yuv use it too. It would seem silly if not down right tedious to type in 40,000++ image names to form a 30 minute video.

ThomasJSmart · Sep 27, 2007

Hi Zeland,

Now the video clip is longer than 1 frame but still no sound, im starting to think there is something wrong with the software on the server that processes the sound part :/

any ideas?

Can you post the command used and the full output of ffmpeg?

Notice my output line, it has 2 streams, Stream #0.0: Video & Stream #0.1: Audio. Yours only has video. This explains why your output doesn't have sound. It could be that your libavcodec/ffmpeg might be stuffed. Try downloading the latest SVN and recompile ffmpeg.

am i missing a config option??

ThomasJSmart · Sep 27, 2007

also interesting if i do audio first then the image, it still only loads the image, its like my audio is being ignored...

converting an avi/mpg with sound to an flv with sound works fine tho >.<

I learned a bit yesterday, today i learned a lot, imagine what i'll learn tomorrow!

zeland · Sep 27, 2007

Well, the first obvious thing to look at is that the error is asking you to compile ffmpeg using gcc >= 4.2. I've compiled mine under 4.1. What ver of gcc do you have?

Another thing that struck me is your ffmpeg build. The config line only states --enable-shared and nothing else. Can you encode a normal .wav file into an .mp3? You may want to passing the --enable-libmp3lame parameter during ./configure and recompile again.
