Application crashes when starting video in browser (galaxy s) #5

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago
What steps will reproduce the problem?
1. start Web Camera
2. start
3. open browser at given url and start player

What is the expected output? What do you see instead?
the stream is expected, but nothing is shown and android application crashes

What version of the product are you using? On what operating system?
android 2.2, galaxy s

Please provide any additional information below.

The crash happens at the following line:
dlen = fis.read(buf, offset + buf_len, target_size); (StreamingKernel.java 220)
A java.lang.ArrayIndexOutOfBoundsException is thrown and not catched. According 
to the documentation: that type of exception is thrown if: offset < 0 or 
length(taget_size) < 0, or if offset + length(taget_size) is greater than the 
length of b(buf).

The values are in my case:
length buf = 65535
offset = 4
buf_len = 0
target_size = 6578548

Similar problem. The receiver input stream starts like this:

00 00 00 00 66 74 79 70 33 67 70 34 00 00 00 00 69 73 6F 6D 33 67 70 34 00 00 
00 18 00 06 2E 08 66 72 65 65 3F 3F 3F 3F 6D 64 61 74 01 48 20 06

....ftyp3gp4....isom3gp4........free????mdat.H .

The word 'free' is at location 0x32, and the parser thinks that is a 4-byte int 
containing the frame-size.

'free' = frame_size: 7497061 =/

Just edit buffer length. note, that you need to edit length in several places.

Thans for your replay. Can you provide me more details on where to change? And 
how can I know which is the correct buffer length?

Thanks!

After some more debugging, i've found that after reading the 32 bytes header, 
the next 8 incoming bytes are 0-0-0-0-[mdat].Isnt this an mdat atom without 
size? (this, is, still not calculated).I've been looking around the web, and i 
know the encoder first writes an empty size header, and later, when the size is 
known (ie, the recording is stopped), rewrites it (if output is sent to a 
file).How is this managed in this project?
