This utility can recover video and audio streams from unfinalized MP4/MOV/3GP files without (or empty) header.
You may got the unfinalized file in case of damaging camcorder during recording or such.

Supported video formats: AVC/H.264, HEVC/H.265

Supported audio formats: AAC, ADPCM (Intel), MP3, PCM (LE, BE, float), RAW

Usage:
recover_mp4 in_good_similar.mp4 --analyze
recover_mp4 in_corrupted.mp4 {out_video.h264 | out_video.hevc | --novideo}
[out_audio.aac | out_audio.wav | out_audio.mp3 | out_audio.raw | --noaudio] [options]
Options:
--start read from position (ignore mdat atom)
--end end position (ignore mdat atom). Specify 0 for EOF
--avcidrmax ignore AVC NAL units (IDR) with the size above than bytes
--avcxmax ignore AVC NAL units (non IDR) with the size above than bytes
--aacmin

--gopro4 use Ambarella templates and detect GoPro4 specific data. Default for MP4 files.
--ambarella use Ambarella templates (ignore GoPro4 specific data).
--qt use QuickTime templates. Default for MOV files.
--eos use Canon EOS templates
--eos2 use Canon EOS extended templates
--vmix use vMix templates
--blackmagic use BlackMagic templates
--g7 use Panasonic DMC-G7
--a7sm2 use SONY A7S Mark II templates
--drim use DRIMeIII templates (Samsung NX1000 camcorder)
--drim5 use DRIMeV HEVC/H.265 templates (Samsung NX1/NX500 camcorder)
--hevc use generic HEVC/H.265 templates
--ext use generic templates for any other camcorder or smartphone

Step 1: Use any good previous file with the same resolution and bitrate to generate the header files, for example

>recover_mp4.exe good.mp4 --analyze

It will create files 'video.hdr' and 'audio.hdr' in the current directory and print instructions (ffmpeg options, etc.).

Step 2: Recover streams from the corrupted file, for example

>recover_mp4.exe bad.mp4 recovered.h264 recovered.aac

Note: Files 'video.hdr' and 'audio.hdr' must be exist.
Probably you need to add a specific option (look at instructions from step 1).

Step 3: Use any other utility (Yamb or ffmpeg for example)
to recreate the MP4/MOV file from the streams (recovered.h264 and recovered.aac).

>ffmpeg.exe -r 30 -i recovered.h264 -i recovered.aac -bsf:a aac_adtstoasc -c:v copy -c:a copy recovered.mp4

Note MP4 does not support PCM sound, you must create MOV in this case:

>ffmpeg.exe -r 30 -i recovered.h264 -i recovered.wav -c:v copy -c:a copy recovered.mov

In case of ADPCM audio:

>ffmpeg -r 30 -i recovered.h264 -i recovered.wav -c:v copy -c:a adpcm_ima_wav recovered.mov

Note: 30 is FPS in these examples. Specify your correct value.
In case of 29.97 I suggest to specify 30000/1001 instead.

Great program. Saved my life.
Only had one hiccup when I tried to use MKVToolnix to merge video and audio (duration was much shorter because it had some problems), but ffmpeg solution posted here did the trick.

Fantastic, did the job exactly as advertised. Invaluable -- since it's free.
Tried to donate, but link is not functional, takes you to Premium service.
