I recorded two videos on a digital camera. Both videos were saved using identical codecs and settings.
The second video is corrupted, in some way, and I can't open with VLC or video-editing software. (The first video is ok).
I tried to convert video with "video to video" software that says:
#8636.3: [h264 @ 04E10060]AVC: nal size -1920576098
#8636.3: [h264 @ 04E10060]no frame!
#8636.5: [mov,mp4,m4a,3gp,3g2,mj2 @ 04EC4020]decoding for stream 0 failed
#8636.4: [mov,mp4,m4a,3gp,3g2,mj2 @ 04EC4020]Could not find codec parameters
for stream 0 (Video: h264 (avc1 / 0x31637661), 1920x1080, 11987 kb/s):
unspecified pixel format
#8636.4: Consider increasing the value for the 'analyzeduration' and
'probesize' options
***File load error: C:\..\PICT0002.MP4: could not find codec parameters
Analyzing with Gspot, on videos (video corrupted on the right: PICT0002):
Can anyone suggest a tool or a method to repair the second video? The size is correct (3 GB), and when I try to open it with VLC, the length seems to be ok (40 min).
Theoretically: Should I change codec-metadata in the file to make it recognizable by software?
UPDATE
tried ffmpeg analysis. command: ffmpeg -analyzeduration 2000000000 -i PICT0002.mp4 -c:v libx264 -c:a copy PICT0002-fixed.mp4
response:

So, the conversion failed.
Judging by the log output, the software you are using appears to be FFmpeg (or based on FFmpeg). Try to add the flag
-analyzeduration 2000000000
to the FFmpeg arguments. It's worth noting the VLC player is also based on FFmpeg... and thus they share similar limitations in their default configurations. – Cliff Armstrong – 2018-06-30T15:43:12.137how to do in windows 10? (tank you) – Marco – 2018-06-30T16:14:18.993
Well, you said you were using "video to video" software to convert the video. What software is that? Does it have a name? If you want to use FFmpeg directly (high learning curve) you can download the latest windows builds here: https://ffmpeg.zeranoe.com/builds/ . It's a command line tool, so you will have to run the "ffmpeg prompt" and execute the appropriate command. Something like:

should do it.http://www.videotovideo.org/ – Marco – 2018-06-30T21:08:40.270
