#11142 reopened enhancement

Bad decoding of MP4 containing differently encoded videos joined

Description

Summary of the bug:
What I trying to accomplish: I want to concatenate multiple almost independent, but having the same format (resolution, codec, pix_fmt and all others), chunks of video, size of which is in a range 1-25.
The problem I encountered: Resulting video cannot be decoded (at least) by libav* and players that depend on it (mpv, vlc).
The exact command line you used:

#!/usr/bin/env bash

set -xueo pipefail

rm -f {1,2,12}.mp4 ffmpeg-*.log
./ffmpeg -f lavfi -i testsrc=s=640x480 -frames:v 1 -codec:v libx265 -x265-params keyint=1:min-keyint=1 1.mp4
./ffmpeg -f lavfi -i testsrc=s=640x480 -frames:v 2 -codec:v libx265 2.mp4
cat >cat.txt <<_EOF
file 1.mp4
file 2.mp4
_EOF
./ffmpeg -safe 0 -f concat -i cat.txt -codec:v copy 12.mp4
./ffmpeg -v 9 -loglevel 99 -report -i 12.mp4 -f null - &>err.txt

͏    Not the same. Mistake.

Component: undeterminedavformat
Keywords: concat mp4 added
Summary: Decoding error for 1-frame concatenated chunks encoded by libx265 if keint=1:min-keyint=1Bad decoding of MP4 containing differently encoded videos joined
Type: defectenhancement
Version: 7.0git-master

͏    The command indicated concatenation of differently encoded videos:
͏    Which most containers wouldn't properly support.

͏    Note different encoding settings of the same codec, maybe no different than different codecs outright.
͏    Woefullest case: different videos of different resolutions...
͏    No sensible general handling (without involve express designation) possible.

The difference only is between 1-frame chunks and non-1-frame chunks. 1-frame chunks are special in this regard.
Seems this is the field of undefined behavior (but I suspect it is very close to become defined, just need some improvement to handle the case (because for x264 there is no such a problem), so this should not be considered as a bug, but as a feature request though).

͏    Different "keyint" settings is more than that.
͏    It's up to the decoder to decide how shall handle alike.
͏    However this is somewhat "Codec container wrestling each other..."

Thank you for the links.
For those who also want to encode video as single-GOP chukns (for me it is needed to encode atlases for VR video) there is a solution: to use keyint=-1.

comment:7 by MasterQuestionable, 4 months ago

͏    "keyint=infinite" preferable: which should also work for x264. ("keyint=-1" wouldn't)

From x265
Invalid value for keyint: infinite.
Invalid value for keyint: inf.
