So I've been trying to make a video player that plays video from the server, right now I wrote a simple code to play a video from the SD card.
but when it calls `avformat_find_stream_info()` It crashes, I can't seem to find any solutions about this and since I'm pretty new to C I don't have any idea about how to debug this.

I'm not sure what to provide, so I'll just upload my source files:
https://drive.google.com/file/d/1d3KAiimB_NMYpRa_kYzLXwi507tWygBJ/view?usp=sharing

`3dsconf_default` is configure script I used to compile FFMPEG. FFMPEG version is 4.3.
crash_dump_00000006.dmp file is a dump from a crash, I'm not sure what to do with this. GDB doesn't recognize this.
Openico3DS.3dsx file is the one I sent to my 3DS. I sent it via 3DSlink, if that helps.
I added a code that waits until user presses A before the code which causes the exception, so You'll have to press A to see exception.
You'll have to put nico.mp4 file to `/ts/nico.mp4` in your SD card to replicate the issue. I haven't checked other video type, but mp4 is the one I will use so I have to debug in this format.

If you're experienced at this kind of thing, please help me. It is so frustrating that I have no idea about what's going on, I can't even attempt to debug it.

EDIT: Here's the crash screen.

Stack dump is empty.

hi, I have same error but I DELETED avformat_find_stream_info() from your code and tried.
It won't crash and I got file info so I think we don't have to call avformat_find_stream_info().

However, I have other problem.
When I call avcodec_send_packet() it returned -1094995529 (0xBEBBB1B7 : Invalid data found when processing input).
Is there any idea?
(I also tried your "nico.mp4" .)

Wow, thanks!

I wasn't able to visit forum for a while, sorry for the late reply.

I currently don't have lots of time on my hand, I could revisit it after 2 weeks at best. but when I do it, I'll make sure to notify you.

Thanks a lot again!

After that I found we need to call avcodec_parameters_to_context() and we need to run these code on another thread or it WILL CRASH.
I don't know why but I created another thread using threadCreate() and tried decoding, it worked fine.

Absolutely stunning. I didn't expect you to investigate further.

I know that I'm really, really late- But I really appreciate your help, and all the times you spent investigating this error.

Thank you so much, kind stranger! I'll be sure to alert you when I make more progress.
