Hi,

very nice tool. There are a lot of features which enable error tracing when modifying existing H.264 encoders (the picture order of the reference lists is a very nice feature). But there is one thing which does not seem to work: opening MP4 files with audio tracks in it - the program hangs for about 10 minutes and then throws an "forbidden_zero_bit set" message, but I'm absolutely sure that this bit is 1 in every NALU of the embedded bitstream.
And by the way: the tool seems to be incompatible with Windows Vista. No matter which file type I open - the only thing I see in decoded frames is "Decoded frame x" where x is the frame's POC.
But concerning the rest (as I said before): very nice tool

Hi Dust Signs,

opening MP4 files with audio tracks in it - the program hangs for about 10 minutes and then throws an "forbidden_zero_bit set" message

I tested with many mp4 files while adding mp4 file structure parsing but I did not observe this problem. Can you send me your mp4 file to h264visa@daydayup.info? I can verify why.

the tool seems to be incompatible with Windows Vista.

En, this seems really bad, I will verify it.

It will be hard for me to send one of the MP4 files because they are all min. 700 MB. I retested with a smaller file and it worked. Maybe there is some problem if the file size exceeds a certain threshhold (I did not yet find the time to figure out which file size exactly).

I see.
In theory the file size should not cause this problem. I will check it.

I have fixed a crash bug and the slice group display bug, and updated to 1.03, please try the latest version(my signature has the download link)

Works fine now with Vista and my MP4 files, thanks . I'll continue testing
