If this doesn't help you will have to reduce the output resolution when
reencoding.

CPU usage may be too much even for your Sempron), this is not a bug in
FFmpeg and this is a bug tracker, not a support forum, sorry.
When I bought my phone last year, I could play the videos almost
flawlessly, just with a few glitches. It began freezing in February 2014.
That's why I didn't imagine that it was just a performance problem and I
suspected that something was broken in ffmpeg. Before filing this bug
report, I remuxed some videos with the same container and with another one
as it was a known workaround for Samsung Galaxy phones but it didn't help.
The only way to work around this "limitation" consists in using mpeg1video
as a container as a first step before converting it into another format.
Moreover, even the videos I made before February were affected, that's why
I suspected that it didn't come from an Android update. I have never
thought that this place is a support forum, I asked for help on the IRC
channel first, the workaround is far from being obvious and I'm not sure
it will help me to put my videos onto Mediagoblin anew. As I use ffmpeg to
convert my videos into WebM before uploading them, I suspected that the
problem came from it. Sorry for the annoyance.
