H264Visa: totally FREE H.264/AVC analyse tool, Christmas Update

[h264visa]

I have released H264Visa (http://h264visa.daydayup.info/downloads/H264Visa.zip) 1.05, with many bug fixes and updates on Pixel Info and Pred Info. With those updates H264Visa can analyze baseline, main and high profile H.264/AVC streams as well as mpeg2 ts and mp4/3gp files. Now H264Visa is on the same level with all the commercial h264/avc analyse tools, and better than them on pixel info display and mb type search, but it is FREE.

Here is the homepage:
h264visa.daydayup.info (http://h264visa.daydayup.info)

If you have any comments or bug reports, please comment on this thread or drop me an email at:
h264visa@gmail.com

Thanks.

Looks interesting. I tried to examine a h.264 stream and Windows (Vista 32bit) reported that "H264Visa.exe has stopped working" immediately after I specified the file type.

If you can provide a debug version of the program, I can load it into Visual Studio when it fails.

[h264visa]

omf,

Can you send your h.264 stream to h264visa@gmail.com? I can have a look for you first.

It crashed on the first h.264 ES stream I opened when I hit play.

[Sharktooth]

yup, same for me. it took a while though.
Faulting application h264visa.exe, version 0.0.0.0, faulting module ntdll.dll, version 5.1.2600.2180, fault address 0x00001010.
ill see if i can get a more detailed crash report.

[h264visa]

It crashed on the first h.264 ES stream I opened when I hit play.
I guess you can open the file and get sps/pps info, but when you hit play/step, it will crash, right? I guess you H.264 ES contains field pictures. the field decoding will be added in the future version in H264Visa.

yup, same for me. it took a while though.
Eh, no idea now, can you provide more details?

[Sharktooth]

not properly an ES, but a 700MB .mp4 file muxed with mp4box.
there were 2 streams, 1 video stream (h.264 HP) and 1 audio stream (AAC+ v2). it opened the file but after seeking few frames it started to slow down and show artifacts in the preview window then it crashed as described above.

[h264visa]

Sharktooth,

It might be caused by bit errors in the demuxed h264 video. Can you send me your mp4 file? I can debug whether this is caused by my mp4 parser or h.264 codec. my mail is: h264visa@gmail.com

thanks.

[Sharktooth]

probably it's the parser.
i re-tested it and this time used the play button. i noticed an "End of stream" message after 65 frames (clearly wrong)... then if i force the seeking again and push forward over that frame it shows artifacts then crashes (also negative frame number in the pixel info window)
i can manage to cut a clip and send it to you, but i have a slow internet connection here. i'll do it when im at home:)

I guess you can open the file and get sps/pps info, but when you hit play/step, it will crash, right? I guess you H.264 ES contains field pictures. the field decoding will be added in the future version in H264Visa.That's right, it had field pictures.

What H.264 decoder are you using?

[h264visa]

I am using my decoder now. in order to retrieve more info freely.

I have found a few streams that crash the same way sharktooth describes. They are all very big though (>100mb). I tried to cut out the first section only, but when I try with these h264visa just quits straight away as soon as I try and open them, rather than crashing the same way.
Can you suggest how I can cut these streams down? Currently I'm muxing to MKV with MKVMerge and using that to output splitted mkvs. Then I extract the first one of those.

looks promising btw :)

[Guest]

I am using my decoder now. in order to retrieve more info freely. You're using it for decoding and displaying the video, too?

[Sharktooth]

since this is an analysis tool, i think you should use the JM reference decoder (the source is available here: http://iphome.hhi.de/suehring/tml/download/)

[h264visa]

Check,

Can you suggest how I can cut these streams down?
I do it using split in cygwin, command line: split some_big_file -b 2m #(split some_big_file into several 2M files)

Neuron2,
You're using it for decoding and displaying the video, too?
No, the display is using SDL.

[survivant001]

I never been able to open 1 h264 with this software.

I'm using 1.07

on WinXP 32bit and XP 64bit

it's always crashing

[h264visa]

I have updated H264Visa to H264Visa Mobile Solution 1.00(download (h264visa.daydayup.info/downloads/H264Visa.zip)),

As the name indicates, this version is only used for analyzing streams/codec for mobile products, so NO support for field streams.
Here are the main updates:
- Fixed the crash on reopen streams/files.
- Added NAL tree analyse.
- Added SEI tree for Picture Timing SEI and Buffering Period SEI.
- Added MB structure overlay for I/P/B MBs.
- Added motion vector overlay for P/B MBs.
- Added Stop and FR.
- Added Summary Dialog for Picture Info, Stream Info(HRD etc)
- Optimized backward playback.
- Picture Enhancement on Residual display.
- Optimized Histogram display.

Please try the new version :)

@h264visa

I been able to open few movies .264 encoded by x264. but there is one in particular taht i'm not able to open.

I'll try to send a sample tonight here (http://www.mediafire.com/?yycxm0gbbv8)

here the command line (in case that can be usefull)
"x264.exe" --pass 2 --bitrate 5879 --stats ".stats" --progress --keyint 24 --bframes 3 --qpmin 7 --qpmax 51 --no-psnr --mixed-refs --trellis 1 --ref 3 --filter 0,0 --subme 6 --direct auto --vbv-bufsize 14000 --vbv-maxrate 26000 --me umh --level 4.1 --weightb --b-rdo --bime --analyse p8x8,b8x8,i4x4,i8x8 --8x8dct --threads auto --thread-input --aud --nal-hrd --me-prepass --sar 1:1 --output "movie.264" "movie.avs"

[survivant001]

@h264visa
does the sample help ?

[h264visa]

@h264visa
does the sample help ?
Yes, it is very helpful. Thanks.
I have identified the problem： some nal size is larger than H264Visa can support. I will fix this bug in next release.
Thanks again for the bug report.

[Gabriel_Bouvigne]

May I suggest a version number within the "about h264visa" box?

[vizzimani]

I just downloaded i have to try. but its very interesting. I used so many tools. to analyze h264 streams. thanks for this.

[vizzimani]

its really excellent. it is very much better than so many commercial analyzing tools. thanks.

[Rectal Prolapse]

Will this work for testing Blu-ray AVC video streams? Thanks!

[h264visa]

Will this work for testing Blu-ray AVC video streams? Thanks!
If the video stream contains only FRAME picture, Yes. otherwise, No, not yet.
