Excellent solution, renaming and then converting fixed my issue! - Thank you
Although I had to take an extra step; I had to ask a colleague to rename the files for me ass it originally worked on his Windows machine but not mine, so there is still an underlying issue on my machine, something is damaging files within the m4a container...
I have this issue, and the device that created the file can’t open it, nor can Q-Time, Nor VLC. The file was captured using a FPV drone camera via Wireless Xmission to my phone, using the software that comes with the camera. It shows the thumbnail of the first frame, and file mgr shows it is a 4MB file. But when I press play, I get a message, 'Sorry, this video cannot be played'. Does the WLAN freq. have anything to do with it? Camera is 5.6 GHz. I have no idea what the phone is.
I have the latest VLC player (2.2.4) and have none of the options you note. I don’t even have 'File'. I have 'Media' where File would be on most apps.
Starting here, I have none of this:
Proceed to click on File — >Streaming/Exporting WIzard...
Go through: 'Transcode/Save to file'
Then: Select either select streaming file from location:
Select File from existing playlist. (Open(ed) files)
Last: Select how you want it TRUELY encoded as anything from mpeg4 video and audio to DivX to H. 264 to Theora REMEMBER: select the transcode buttons.
(Don’t forget bitrate has an extreme importance the more bits the higher quality but it comes at a price as the video becomes larger. It won’t be 100% quality, maybe 95% max; usually around 85 - 90% normal quality.)
Next: select your encapsulation method you want this to match your codec so please match them, it causes less problems.
Almost Done: Select a save location and wammo your done!
Finally: Click FINISH and it shows you all your work one last time before you complete the transcode.
So, where do I find this stuff? (See screenshots)
