Well, I don't have much experience with longer, self-created H264 video files. So I started, as per another thread, some speed-quality related experiments.
I've taken a longer MPEG-2 file (41:32), encoded it with these options:
x264 - core 54 svn-635M - H.264/MPEG-4 AVC codec - Copyleft 2005 - http://www.videolan.org/x264.html - options: cabac=1 ref=3 deblock=1:-2:-2 analyse=0x3:0x112 me=hex subme=1 brdo=0 mixed_ref=1 me_range=16 chroma_me=1 trellis=0 8x8dct=1 cqm=0 deadzone=21,11 chroma_qp_offset=0 threads=2 nr=0 decimate=0 mbaff=0 bframes=3 b_pyramid=1 b_adapt=1 b_bias=0 direct=1 wpredb=1 bime=1 keyint=250 keyint_min=25 scenecut=40(pre) rc=crf crf=24.0 rceq='blurCplx^(1-qComp)' qcomp=0.60 qpmin=10 qpmax=51 qpstep=4 ip_ratio=1.40 pb_ratio=1.30
This file is fully seekable.
I encoded the audio separately, with Nero AAC, then I did:
mp4box -add audio.mp4 filename.mp4. It crashes in the second part, in module ntdll.dll.
R:\AUTOMKV_LATEST\exe\Matroska>mp4box -add F:\dcv\ok\1\audio.MP4 F:\dcv\ok\1\fil
ename.mp4
IsoMedia import - track ID 1 - Audio (SR 48000 - 2 channels)
Saving F:\dcv\ok\1\filename.mp4: 0.500 secs Interleaving
MP4Box - GPAC version 0.4.3-DEV

Yamb 2.0, created the file, but it is not seeekable anymore, probably after the first 20 minutes (1/2).
Please, what can I do now?
I would like to:
- check the MP4 video only if there are any corrupt frames
- check the AAC audio if there are any corrupt frames
- try another muxer, or
- even get the raw H264 stream from the MP4 and do the above mentioned
Everything must be able to run on Windows XP Professional, no Linux/Unix only please, command line utils are okay.
Thank you for the links and suggestions. The only other option is redoing it all :rolleyes:
EDIT:
Highlighted in blue, how to check for erroneous a/v frames?
