Hi Laura, > Can you tell me which players work for you? I tried with my browser > and it still tells me that the file is corrupt :/
I have tested Parole and Videos media players and Firefox and Midori browsers. All work except Firefox, which gives the message: 'Video can't be played because the file is corrupt' Is Firefox the browser you are testing with? Possibly another tweak to the ffmpeg encoding might be needed to support Firefox. > I didn't notice this. Is it possible to make the audio shorter than > the first duration? Ah, the expression for duration1 should be: duration1 (in seconds) = number of frames / 25 What I was thinking was that the cli sessions should end with a short pause. This will be the case as long as either duration1 is greater than duration2 or the audio file has a silent section at the end. If any of the transitions are too abrupt we can add some silence to the relevant audio file. The command I used for the silent slide in 02- daily-use2 was: $ ffmpeg -f lavfi -i anullsrc=r=4800:cl=mono -t <ts> -q:a 9 -c:a libmp3lame <audiofile>.mp3 This creates an mp3 file with <ts> seconds of silence. So a one second pause, say, could be concatenated (with ffmpeg) at the beginning or end of an audio file to improve the transition. Best regards, Paul.
