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.

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