Use JSON output from ffprobe #18

Closed alycda closed 2 years ago

alycda commented 3 years ago

use JSON-output of ffprobe for parsing instead of Regex to parse to Human-readable ouput

(I'm new to python, go easy on me)

still getting the following error:

Thanks for the PR! I just tested it (on just a single file), and everything seems to work!

All the errors you are getting are related to the badly defined entrypoint, which is fixed in #15.

I copied over your changes from #15 into my local, I see the following resolved:

But I guess my "test.mp4" is still corrupt:

I'll continue to dig to provide better error handling in this case. Thanks for your input!

Hm, curious. Have you tried extracting the data with another tool (https://goprotelemetryextractor.com/free/)?

Seems like your problem was entirely unrelated to ffprobe, there is something going wrong while decoding the data. Unfortunately I haven't looked into the details of decoding.

Can you upload the extracted data stream (as described in the Readme)?

alycda commented 3 years ago

Hm, curious. Have you tried extracting the data with another tool (https://goprotelemetryextractor.com/free/)?

Yes, I typically use this tool, however I was experimenting with my own custom lambda. I don't recall how I created "test.mp4" (pretty sure I just exported a 30 second clip from the GoPro iPhone app) so that I could work with a smaller file. The giant (4gb) file is working though, so I'll keep better track of how I source my files.

The source code for goprotelemetryextractor is available on github, https://github.com/JuanIrache/gopro-telemetry#readme, but NodeJS was running out of memory for large files. I believe test.mp4 worked with that tool, but I intended to write my lambda in python just as a learning experience (and it's not encountering memory errors).

@juanmcasillas

I have the same issue, 3.7GB, Hero 8, original file from camera https://goprotelemetryextractor.com/free/ exports GPX just fine... But gopro2gpx cant get gpx from it.
