There's a set of AVIs I would like to eventually convert to MP4 format for watching on small-display devices. But for now I am getting to grips with the different codecs and formats, and have simply been providing the video with a new container using ffmpeg or my new best 'friend' Xmedia Recode'.
I have three pretty similar AVI files from ripped DVD (say A, B and C) that I would like re-container (i.e. copy acodec and vcodec). It works for one format (file C), but not the other two, in the sense that mediaplayer such as MPC-HC only plays the audio and not the video of file A.mp4 or B.mp4. I am trying to better understand link between content and container. What is the reason behind the video A and B not being compatible with their new MP4 container?
Many thanks for any feedback.

I don't see anything in the video that looks problematic. What about audio codecs?

I can copy acodec or convert mp3 to aac, but this does not affect playback or solve the problem with A and B.mp4. Thanks Jagabo.

Will install Mpeg4Modifier and let you know. Cheers.

Sorry, I was wrong about MediaInfo not showing packed bitream. It does list the feature if it is used in the file. So that's probably not your problem.

No packed bitstream for all files, I'm afraid...

If you told me one file didn't play after muxing into MP4 I would have guessed C. Some old devices didn't support B frames and custom matrices. And C is the highest Profile But that's the file that does play. The other two are simpler and shouldn't have problems. All I can suggest is you try reencoding with and without the different settings until you find what's causing the problem for your device.
-
All I can suggest is trying a different program.
MyMP4BoxGUI should do it.
If you open an AVI to remux it, it'll only display the video stream in the GUI which gives the impression the audio needs to be added separately, but that's not the case. You should just be able to add an AVI and re-mux.
MP4Box can be a bit finicky sometimes. It doesn't seem to like AVIs where the audio stream contains junk data (some AVI muxing programs add it) and it'll start muxing and then quit for no apparent reason. It's still be worth a shot though.
I use Video To Video Converter for "odd job" remuxing quite a bit. When you add a file for conversion, it'll open a window and ask you to pick a conversion preset. "Direct Stream Copy" (the last on the video profiles list) would be the one to try. All you need to do is select it, then choose your desired output container on the right. It adds the job to the conversion list, but it just copies the video and audio, despite the need to click on "convert".
You can open a bunch of files or a folder of them for batch conversion. It's managed to remux files for me quite a few times the usual methods have failed. It probably uses ffmpeg for a lot of the work, but you never know..... -
Many thanks for the suggestions jagabo & hello_hello.
Yes, it's peculiar it's both the A and B MP4 that do not play whilst C is fine. I was not able to find the exact cause.
So what worked?
MyMP4BoxGUI was able to generate a new MP4 container that played in MPC-HC but not in WMP. To play an MP4 in a range of mediaplayers I needed to transcode.
Also thanks for the Video2video converter suggestion. A great new tool for my box! -
It still seems odd, having to transcode.
Did you try any of MyMp4BoxGUI's options? There's a couple for making MP4s "apple friendly" and a few others under options/advanced. Maybe you could try one of these?
-isma: converts file to ISMA 1.0 specification. This is extremely useful since most MPEG-4 players only understand ISMA-like content. All systems information and tracks numbering are rewritten to comply to the specification.
WARNING: some media tracks may be removed.
-3gp : converts to 3GPP specification. This will remove all MPEG-4 Systems information, leaving only the audio/video/text media tracks supported by 3GPP. This option is always turned on when the file extension is ’3gp’ or ’3g2′.
WARNING: some media tracks may be removed.
MeGUI has an MP4 muxer under it's Tools menu. I didn't mention it as it also uses MP4Box for the work, but it offers the ability to select device compatibility. For example if you select "iphone" it adds the following to the commandline: -ipod -brand M4VP:1
I couldn't seem to find it in MyMP4Box's command line options.
I don't use MP4 but I remuxed a few AVIs and couldn't output one MPC-HC or WMP wouldn't play, but I didn't try any other devices. The version of WMP I have is the one which comes with XP. I never use it, but it's so old it doesn't even recognise the MP4 file type and asks if you want to open an "unknown file extension". It still plays the AVIs I remuxed though (with the Haali media splitter's help).
