MP4 file from raw H.264 input

[indorian]

Hi,

I am getting H.264 encoded frames from camera->mediacodec and would like to use MP4Parser to create .mp4 from this data. Is it possible to use MP4Parser to create files from raw frames, not from existing MP4 file?

Thanks in advance!

Hi Sebastian or Indorian,

I am trying to achieve the same. I can generate basic h264 files with my Android app that Totem Movie Player (Linux Mint) will show correctly. But trying to add these tracks to a MP4 "Movie" gives me the following exception:

java.lang.NullPointerException

at com.googlecode.mp4parser.authoring.tracks.H264TrackImpl.readSamples(H264TrackImpl.java:283)

at com.googlecode.mp4parser.authoring.tracks.H264TrackImpl.parse(H264TrackImpl.java:87)

at com.googlecode.mp4parser.authoring.tracks.H264TrackImpl.<init>(H264TrackImpl.java:76)

at com.plusot.osee.encoder.MP4Builder.buildMP4(MP4Builder.java:27)

at com.plusot.osee.EncoderActivity$1.run(EncoderActivity.java:100)

at java.lang.Thread.run(Thread.java:856)

I am afraid that the h264 file I produce with the Android MediaCodec is missing something. But what is missing? I have attached source from "MP4Buider.java" and  "VideoEncoder.java".

Any help will be very much appreciated.

Best regards,

Hi Sebastian and Indorian,

Solved it myself. I was using the MP4Parser from the Nexus master source tree (http://source.android.com/source/index.html). Updated it with the newer version and the problem was gone.

Peter

Peter,

How did you get this to work?

The H264TrackImpl takes and InputStream and building the movie throws an IOException because FileInputStream does not support read/mark.

This is logged as an issue https://code.google.com/p/mp4parser/issues/detail?id=40

Did you get this to work? Did you find a workaround?

If so please let me know...I'm stuck.

Thanks,

Bill

Wrap it with a BufferedInputStream or use the latest version which uses a FileChannel instead of a stream!

Hi, Im curious, 

Current version of the library is using FileChannel interface only, no BufferedInputStream, so I can't create H264TrackImpl from BufferedInputStream in the latest version of the library, so how i can write my encoded frames to H264TrackImpl on android? Should I rewrite ur library by myself to add support of BufferedInputStream?

Also question about isoparser-default.properties, should this file always be present on my android device, no default values?

Please do not copy my source code into your project. Please depend on the jar as you will have less problems, the jar includes the properties file at the right place. Promised!

FileInputStream fis = new FileInputStream(“c:\file.mp3”);

new H264TrackImpl(fis);

 

Fails as FileInputStream doesn’t support mark/reset

 

FileInputStream fis = new FileInputStream(“c:\file.mp3”);

new H264TrackImpl(new BufferedInputStream(fis));

 

succeeds as wrapping it with BufferedInputStream adds support for mark/reset.

Thanks for the answer, what jar ur talking about? Is there prebuild version exist?

I've downloaded sources from https://code.google.com/p/mp4parser/source/checkout and trying to make it work in my android project in eclipse.

Hi Peter!

Could you be so kind to share the source code of your sample project?
I cannot even get past the encoding phase. 

It seems like you are one of the very few people (if not alone) who was able to get this to work.

Thanks in advance,

Paul

[Peter Bruinink]

Hi Paul,

I am away for a few days. As soon as I am back, I ll share the code.

Hi Paul,

I can't seem to find the discussion on groups.google any more. What is your problem in in encoding?

Peter

hello Peter 

can you provide the updated version of mp4parser . i searched a lot but could not find it.

you can mail it at ma...@ebabu.co

[Peter Bruinink]

Hi Mansi

I am on vacation now. I will need to have a look. I think it is in the Android sources ( source.android.com) as third party software.

Regards Peter
