I've been trying to convert a sequence of PNG files to a video with some
sound (mp3 or wav).
It pretty much works with different codecs and quality settings for both
video and audio.
But the audio disappears somewhere in the middle of the process
E.g. here's my options (I tried copying audio, encoding to various codecs
from mp3 and wav with various bitrates etc - all with the same result):
ffmpeg -report -threads 0 -f image2 -i "files/%%d.png" -i "audio.mp3"
-start_number 0 -frames 1500 -vcodec mpeg4 -q 20 -acodec copy -r 25 -y
"video_out/seq.mp4"
this gives me a video with the problem that audio stops being played
about half way through.
Here's the output from ffmpeg: http://pastebin.com/cgWqhK2A
I can't see any strange issues there.
Please let me know if you know where this could be coming from. I've been
banging my head for a long time trying to resolve this.
I'm on FFMPEG for windows (Feb 1 2013 18:47:10 with gcc 4.7.2 (GCC)).
Thanks
