I am trying to merge a thumbnail-size (104x80) image into an audio file (M4A). I want it to be played in JW Player, but it doesn't seem to support thumbnails. I have tried it in VLC Player, but the image size gets blurred and upscaled.

I am using the following command:

ffmpeg -i image8.jpg -i file.m4a -acodec copy test.mp4

The output of the command:

command line output

How can I merge an image into the audio file so that it works in JW Player and isn't upscaled?

It looks like you are able to embed the image in the audio file just fine, but it's the apps you are using that read the audio that don't support it (properly)? Which images are you wanting to show in your question? You seem to have 4, but only 2 URLs are showing (and the first is incorrectly formatted). – w3dk Apr 12 '13 at 8:41
The full commandline output would be preferred... you can dump it to a plaintext file with ffmpeg -i image8.jpg -i file.m4a -acodec copy test.mp4 2> file.txt, and then paste it here – evilsoup Apr 12 '13 at 9:22

If you were working with MP3, or FLAC, or OGG, or... any other audio format than M4A, the ffmpeg method you are describing would work perfectly well. As it is, for some reason M4A files store the album art in a different way, so you'll have to use a different tool to add in the album art, like AtomicParsley:

AtomicParsley input.m4a --artwork cover.jpg --overWrite

If you are actually trying to create a video by combining the audio and image, then your ffmpeg command should work perfectly well... are you sure it's not just the player software upscaling the video? Try running

ffplay test.mp4

...and see if it comes out the correct size (ffplay is a simple video player bundled with ffmpeg, by default it doesn't do any fancy stuff like upscaling).

@vijay: What's the exact error you're getting? AtomicParsley is a nice program, so you should probably investigate and try to fix whatever problem's preventing it from working. – Karan Apr 12 '13 at 14:57

@vijay: I was talking about your comment above - "i tried using atomicparsley but temp file doesn't create". What does this mean? Do you see a specific error? I'm sure AtomicParsley will do what you want, so perhaps you should look into what's causing problems with it on your PC. – Karan Apr 12 '13 at 16:41
@vijay If you're using JWPlayer, then the problem is in JWPlayer. Your video is not upscaled in FFmpeg. evilsoup, the OP doesn't want artwork; they want to show a plain slideshow-type video with one image and audio in in the background. – slhck Apr 13 '13 at 9:11
