Do you specifically need the MP4 container format? Please show the complete console output from your second command.

comment How to put border around video to prevent clipping of content
@AmadeusDrZaius If the input audio is compatible with the output container format, then consider stream copying it with -c:a copy instead of re-encoding.

comment overlay transparent animation over video with ffmpeg
By default the overlay filter will output yuv420, so when working with RGB you can add the overlay format option such as overlay=format=rgb to avoid any issues caused by the RGB to YUV conversion.

comment ffmpeg using “-shortest” flag, file ends up longer than input file
Yes, this is always the first step when encountering a problem with ffmpeg. See FFmpeg Download page for builds, source code, and other options.

Regarding the libilbc repository mentioned in the FFmpeg docs: running autoreconf -fiv will create the configure file.

comment Merge subtitles and MP3 with blank video
Oh, you're using avconv. Barf. At first I thought you had a MP3 file and a SRT file and you wanted to create hardsubs on a black background which I doubt avconv can do (ffmpeg can). But now I see that your inputs are MP4 and SRT. Now I'm confused as to what exactly you want. Hardsubs? Softsubs? Blank video, video from MP4?

comment Merge subtitles and MP3 with blank video
@Davidenko Pavtube distributes the FFmpeg libraries in a way that violates the (L)GPL. Thanks for mentioning them. I'll add them to the list of violators (much of it is similar software; probably all from the same clowns).

comment Merge subtitles and MP3 with blank video
What exactly are you trying to do? Which Apple devices do you want it to be playable on? Also please show some info about your inputs and your ffmpeg version. The complete output of ffmpeg -i subtitles.srt -i audio.mp3 will be useful.

comment Converting DVD subtitles to text
I've never seen a MP4 file with SRT subtitles. Please show some information about your input and your ffmpeg build so we know what you're working with. The complete output of ffmpeg -i input will be helpful.
