Ok, granted.
Still, I gotta be fair, having an indexer that doesn't create an index file means that it's faster to open in AVS however I wouldn't take the risk on MP4 files from somewhere from the web 'cause bad things can happen like in this case. On the other hand, when I receive .mxf files of 1.3 TB as UHD Masterfiles it could be useful as it would save hours of indexing time (assuming that the index inside the container is correct).

So, in a nutshell, I'd like LSMASH to support MXF as well one day, but for anything that doesn't come from a professional studio, I wouldn't take any chances and I would use an indexer that indexes the file.

He did investigate the issue.

The video file is invalid in that the last two frames both contain the same
poc (26).
ffms2 ignores the error but lsmas is more picky.

ffms2 does work for GoPro videos, but in some cases, the frames in the source video don't match the frames in the output. Something gets skipped. That's probably due to the same issue.

Is there any way I can open GoPro videos without such glitches?

Any chance of a link to the video? I looked but couldn't find it.

Here's a sample video

I just converted a GoPro 5K HEVC video to UT Video with FFMPEG and it gave this list of errors:
- Using non-standard frame rate 29/1
- deprecated pixel format used, make sure you did set range correctly
- Duplicate POC in a sequence
- Error parsing NAL unit #0
- Error while decoding stream #0:0: Invalid data found when processing input

...

Seems to work fine with DGDecNV.

Who's the current maintainer of LSMASH and in which repository can I open an issue on Github about LWLibavAudioSource?
It used to be HollyWu but if I remember correctly last time he retired... so... who's handling this now?

Just creat an issues and Asd-g will fix it

Yes, but I didn't know where, I mean in which repository xD

In the end, I figured it out and I opened it here:

https://github.com/AkarinVS/L-SMASH-Works/issues/17

I feel like I'm always the only one who comes up with Indexing bugs on weird audio codecs like last time with IPCM.
This time is DolbyE ehehehehehe

It's for Vapoursynth and AkarinVS won't support avs, just creat issue here for avs

Opened a new bug about a ZLog2 HDR H.265 UHD file (yes, there's more than just PQ and HLG in the world ehehehe): https://github.com/AkarinVS/L-SMASH-Works/issues/18

Uh, a new version, it's always nice when indexers are updated!

I have a question, or rather a feature request: when an .xml is given to the indexer like LWLibavVideoSource("CPL.xml") and LWLibavAudioSource("CPL.xml") please try to use the IMF decoder built into FFMpeg rather than return an error.
That would be really cool as this way we're gonna have IMF support inside Avisynth!

Done.

Tiny cosmetics, don't remember when it sneaked in.
At first opening and indexing the resampler rate default seems to be uninitiated:

a=LWLibavAudioSource("F:\file.avi"

"LWLibavAudioSource: Failed to open resampler"
but indexes anyway.
Reloading after indexing throws no error.

I have the same problems when PCM audio stream is included in the video.
Have reported this here: https://github.com/HomeOfAviSynthPlu...orks/issues/20

[Emulgator]

Yes, confirmed: In my case PCM Codec ID "twos" Big Endian/Signed 16bps@48kHz wrapped in .MP4 from a Panasonic DC-GH5.

Sorry, I've been a bit overwhelmed. Testing first thing tomorrow, I promise.

Looking forward to that one:
