After upgrading mplayer to 2.4, I was unable to play h264 videos with
the tag major_brand=qt made by several cameras.
I discovered that I could create a h264 file using ffmpeg-1.0.1 and x264
(yesterday's snapshot), and recreate the mplayer problem. Since this
version of ffmpeg is old (but very functional), I upgraded it today.
Unfortunately instead of fixing my problem, this made it worse. Now I
can't create _any_ videos that work correctly, even down to the mjpeg
codec. They are all grey with blocks drawn down from the top.
ffmpeg-2.4 -v 9 -loglevel 99 -i 20140128_pond-W_rec10990.mov -c:v h264
-s 640x360 -c:a copy 20140128_pond-W_rec10990-640x360.2x264.avi >
Regression test: Exact command:
ffmpeg-1.0.1 -v 9 -loglevel 99 -i 20140128_pond-W_rec10990.mov -c:v h264
-s 640x360 -c:a copy 20140128_pond-W_rec10990-640x360.1x264.avi >
anything made with ffmpeg-2.4 is grey and corrupted with errors, whereas
the ffmpeg-1.0 videos are good.
Playing any file with ffplay-2.4 is grey and corrupted, even older
videos that are fine, now play as bad.
Playing the above files in an older mplayer or ffplay work fine with
older videos and the original video, but not the one made by ffmpeg-2.4,
or the ones made with ffmpeg-1.0 and x264.
Also confirmed when loading 20140128_pond-W_rec10990-640x360.2mjpeg.avi
Looking at mplayer output:
The only real difference, is the line
My system information can be found in my request for help from
I assume some library is too old, but not checked in the configure
script. What else could cause this?
