Seems stream 0 codec frame rate differs from container frame rate: 50.00 (50/1) -> 25.00 (25/1)
Input #0, flv, from 'demo.flv':
  Duration: 00:00:30.83, start: 0.000000, bitrate: 546 kb/s
    Stream #0.0: Video: h264, yuv420p, 640x360 [PAR 1:1 DAR 16:9], 546 kb/s, 25 tbr, 1k tbn, 50 tbc
    Stream #0.1: Audio: aac, 44100 Hz, stereo, s16
Output #0, image2, to 'demo.jpg':
    Stream #0.0: Video: mjpeg, yuvj420p, 640x360 [PAR 1:1 DAR 16:9], q=2-31, 200 kb/s, 90k tbn, 1 tbc
Stream mapping:
  Stream #0.0 -> #0.0
Press [q] to stop encoding
av_interleaved_write_frame(): I/O error occurred
Usually that means that input file is truncated and/or corrupted.

Solution 1

I've come to the same error message and have found my (silly) mistake.

As silly as I was trying FFMPEG to create a new directory. Got the error message. Read here. Created the folder myself. Re-run the command prompt and voilà, no more error messages.

The silliest mistake on earth. Just in case someone gets the same error.

Solution 2

av_interleaved_write_frame(): I/O error occurred
Usually that means that input file is truncated and/or corrupted.

Isn't that a clear enough error message? Have you tried with a different input file?

Update: It could be that your PHP script doesn't have the necessary rights to read the file. Try setting the file's permissions to 777 to see whether that's the reason.

Solution 3

I got this error when I accidentally did this

ffmpeg -i vid.mp4 '%05.jpg'

instead of the following

ffmpeg -i vid.mp4 '%05d.jpg'

which is the correct format for sequential filenames (note the added d).
