Summary0000512: Exit silently when scanning capped HEVC 4k in TS files
DescriptionThe video in question is a commercial capped from a 4k TV station, broadcasting free of charge at that moment.

When scanning this file using eac3to 3.32, it exits silently after a fraction of second.

eac3to 3.31 was working partially since it does not try to parse HEVC stream, and at least the audio can be extracted correctly (without correct audio delay detected, of course).

The same issue applies to all similar video clips, HEVC+AAC inside TS files.
Steps To Reproduce1. eac3to 4k-test.ts
Additional InformationAlso expect eac3to to detect the correct audio delay so we don't have to manually sync video with audio.
TagsNo tags attached.
eac3to Version3.32

With that TS file eac3to reports "The format of the source file could not be detected" on my PC. Maybe the file is too short?

My apologies, when cutting the file to get around the size limitation I seemed to cut in a weird position.

Double checked this time and uploaded a new sample.

Thank you for your time.

Is it fixed in this build?

Hopefully fixed in v3.33?

The attached file was too short to properly detect the HEVC properties, but at least it doesn't exit silently, anymore.

I'll upload a longer example for further testing. Also I'll report if the audio delay is correct after comparing with my previous test.

Should be long enough for HEVC properties.

Regarding the audio delay, here's what I ear-detected against videos encoded with DGNV avisynth source filter.

01.ts: eac3to reports -1063ms, ear detected -700ms.
02.ts: eac3to reports -652ms, ear detected -600ms.
03.ts: eac3to reports -1040ms, ear detected -600ms.
04.ts: eac3to reports -601ms, ear detected -650ms.
05.ts: eac3to reports -713ms, ear detected -750ms.
06.ts: eac3to reports -613ms, ear detected -600ms.
07.ts: eac3to reports -570ms, ear detected -450ms.
08.ts: eac3to reports -882ms, ear detected -850ms.

Since those video clips are just landscapes with music, no accurate sync point can be found. And we wouldn't know how DGNV determines its first usable frame either, so this is for reference only.
