A Video File That Plays Only on Osmo4

[ConverterCrazy]

Hello,

I have a video file that plays ONLY with Osmo4 player.
Osmo4 player gives this info:
Object Descriptor ID 1
Duration 29:44:02
Video Object: Width 1920 - Height 1080
Media Codec FFMPEG h264 - version Lavc55.52.102


All other players/rippers/converters (free versions only) exit without 'touching' it.

Even MediaInfo reports one track and no other info. No info about video or audio or codecs or duration.

MKVTools reports "no tracks".

Vidcoder reports : an error occurred while scanning.

The file size is 4.78GB!

My problem is that I use PotPlayer/MPC/VLC — in that order — and the video doesn't play in any of them.
I also tried changing file extension with MP4, AVI, MKV, but nothing worked.

The question is why other players don't play the video while Osmo4 can?

I can't even upload a clip as no tool opens it.

Thanks.

P.S. Osmo4 player comes with GPAC.

Sounds like a raw H.264 stream. What's the current extension - .264?

Get ffplay and run ffplay -f h264 file.264

Thanks. Tried. Doesn't work.

Have been searching internet for some solution. This thread talks about "lavfpref demuxer" http://forum.doom9.org/showthread.php?t=138725&page=31.

Trying to understand. Sounds too technical for me.

That link is from 2010 - a lot has changed in ffmpeg libs since. Paste the full readout of ffprobe -analyzeduration 50M file.ext

Does it help?

[mulvya]

Yes, it's a matroska file. Rename it to extension MKV and then run

ffmpeg -analyzeduration 50M -i duuriyan.mkv -c copy -map 0 duuriyan-new.mkv

[ConverterCrazy]

Thanks a ton!

It worked.

Pl explain what "50M" and "-map 0" mean in the command-line for my knowledge.

Thanks.

-map 0 tells FFmpeg to process all streams in input #0, the first input, which is here the only input.

-analyzeduration 50M tells FFmpeg to probe upto 50 seconds of data within the streams of the next specified input. The unit for this option is microseconds.

Your suggestion worked like magic.

1 – If you have time, pl have a look at #12 https://forum.videohelp.com/threads/372865-Good-GUI-audio-encoders-AAC-7-1-encoding?p=2...=1#post2440558. Can you suggest something? And

2 – Can you suggest how to use dithering in audio to clean irritating and annoying eardrum-jarring sounds while not changing the duration and sync with video?

Thanks.

Dithering is not a tool meant to help with such sounds.

Is it "eardrum jarring" because it already has much distortion? If so, basically nothing can help that (maybe extreme notch/harmonic filtering, or advanced deconvolution, or synthetic adsr-followed replacement).

I am not qualified to explain… it's just an arrow in the dark because I landed here http://www.darkroommastering.com/blog/dithering-explained#comment-5920.

A sample is uploaded here https://forum.videohelp.com/attachments/36465-1460289211/Sample1.zip

I thought it might be due to dithering.
From my side I have tried by applying many effects using Audacity but to no avail.

Thanks for replying.

[Cornucopia]

Dithering is a preventative measure for eliminating correlated distortion, it is NOT a post-corrective remediation measure. Once distortion is IN the signal, it's very difficult to get out, partly because it is part of the signal now, and it is related to the signal (so is not easily discernible for separation from the wanted signal).
Just think if your favorite tune was recorded but that one of the official singers was tone deaf that day even though they tried to follow along, yet they released a version of the song like that. You know it's WRONG, but it's the same singer as should be there, it's in roughly the same vocal range you would expect, it vaguely follows the beat. And that actually can make it MORE noticeable than if it were some steady background thing, because it is in the forefront of your attention focusing faculties, along with the wanted tune.

That clip you referenced has intermodulation distortion, possibly due to low original bitdepth (4-8bits), or it was badly processed and someone used a setting similar to ring modulation that intermodulated the signal with itself, or maybe it was just meant to be distorted that way for effect.

Thanks for explaining.

Indian DVDs are just crap. No professionalism in them. It's not only the bad technicians who master those DVDs but the producers who want the job done 'fast' who'd say, 'abay quality kaun poochhta hai?' (Who the hell — meaning consumers — cares for quality). And the producer is right!

I was hoping against hope. I have bought over 20 DVDs with such crappy sound quality. What a waste of money.

I'll probably, stop looking for solution.
