Gyan,
just wanted to let you know that mp4box has been fixed. They actually had a
fix for me to test by Friday, but I didn't see the message until Saturday
and couldn't test before Monday. As of yesterday both versions are fixed,
and the fixed versions can be found here:

William,
thanks for the reply but mp4box has been fixed and I got a test version
from GPAC support on Friday. So I'll just stick with that.
I went to the site you suggested but the site was out of date, the last
update was in 2013. I could not find anything about command line options in

Gyan,
the problem has been solved! I had reported a bug with the GPAC support
site, and someone named A. David got back to me on Friday to let me know
he/she thinks he fixed it.The email was in my spam folder and I didn't find
it until Saturday, but man was I surprised and relieved to see it.

Unfortunately, I ran into a serious problem with the solution you provided,
Gyan.
I don't recall if I mentioned already that the 64 bit version of mp4box I
got from https://gpac.wp.imt.fr/downloads/gpac-nightly-builds/ doesn't work
at all for me. I always get a message from Windows saying the appli

Carl Eugen,
My supervisor told me that this happens only when we save the video to a
DVR after recording it, and then download it to a PC to play it. If the
video is NOT saved to the DVR, i.e. downloaded to the PC from the video
camera, the video is fine and conversion/scaling is no problem.
I ho
Thanks Gyan!
You are a life saver! I really want you to know how grateful I am that you
helped me with this problem. I had tried so many different ways to get this
solved and got nowhere. I asked for help on the superuser group, but got
none. I tried different converters but it seemed there was alw

The 2nd command in my original post (where I presented this method).
It is,
ffmpeg -v verbose -i hd_video.h264 -i hd.avi -map 0 -map 1:a
Thanks Guam,
That helps, but I don't see the second command to get the audio or use
ffmpeg to play the video.
Did something get truncated, or did you forget to type it?

is causing problems?

You have to run
mp4box -aviraw video hd.avi which will create hd_video.h264
The h264 file cannot be played by many (most?) players but it can be used
by ffmpeg, as shown in the subsequent command. The h264 file only contains
video, no audio so it has to be combined with the audio from the o
Gyan,
I am having trouble with mp4box and I am hoping you can help me once again.
I downloaded and installed the 32 bit and 64 bit version of GPAC but when I
try to run either one, I get errors or a file that won't play. I am running
mp4box on the cmd line using this command:

Could you elaborate?
FFmpeg decoders (and demuxers) were written with the intent to
read as many non-standard files as

Gyan,
thanks for getting back to me and taking the time to explain.
I am not sure how they are produced, except that someone takes a video, it
may be stored on a DVR before it is downloaded to a PC, but it could be

Thank you Moritz! I will at least consider doing that, but I was beginning
to suspect a bug myself. I just need to find a solution or work around
first before I can take the time to do some more testing with VLC to
confirm a bug. VLC allows you to use ffmpeg to convert a video from the

Gyan,
I am still very new to video conversion and ffmpeg, so I don't understand
parts of your reply. Please explain:
What is non-standard about my input video?
I ran many conversion commands, and listed several of them in my original
message. Which one did you use?
What does "Muxing to TS" mean
crf stands for constant rate factor. Allowed values are between 0 and 51,
default is 23. To get better quality, use a lower number. The recommended
start value, if the default does not work for you, is 18. 0 is lossless.

I'd be interested to know what "crf 23" actually means.
How do I get it to do, say, 2.5Mbps?
