[BUG] premature EOF in certain combinations

[kiaraly]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

I'm trying to transcode audio while copying subtitles and I get EOF after the intro ends, skipping the entire rest of the video. Up until 8.1.2 this worked, but the very next release, 9.0, doesn't.

Input file has

• trueHD audio
• ac3 audio
• pgsub subtitles

Selecting just ac3 and copying subtitles works, but as soon as I use trueHD in the inputs the bug appears. Someone else seems to have a similar issue at https://code.ffmpeg.org/FFmpeg/FFmpeg/issues/24336

I have tried and failed to reproduce it with system packages. I can run ffmpeg 9 there and everything works.
I have also tried basing off commit d2c4df5 and just updating the ffmpeg version in the dockerfile, which also didn't work though I may have done something wrong.

Expected Behavior

New versions should handle it as well.

Steps To Reproduce

Transcode a video file with truehd/DTS-HD MA audio and pgsub subtitles. My test command was

podman run --rm -it -v ./:/work lscr.io/linuxserver/ffmpeg:9.0-cli-ls77 \
 -i /work/input.mkv -map 0:3 -c:a:0 libopus -b:a:0 256k -map 0:s? -c:s copy /work/test.mkv -y

with the source file looking like this

● Video  --vid=1  --vlang=eng  (h264 1920x1080 23.976 fps)
● Audio  --aid=1  --alang=eng  'Surround 5.1' (truehd 6ch 48000 Hz) [default]
○ Audio  --aid=2  --alang=eng  'Surround 5.1' (ac3 6ch 48000 Hz)
○ Audio  --aid=3  --alang=jpn  'Stereo' (truehd 2ch 48000 Hz)
○ Audio  --aid=4  --alang=jpn  'Stereo' (ac3 2ch 48000 Hz)
○ Subs   --sid=1  --slang=eng  (hdmv_pgs_subtitle)
○ Subs   --sid=2  --slang=eng  (hdmv_pgs_subtitle)

Environment

- OS: Gentoo/Debian
- How podman/docker service was installed: System packages

Docker creation

Working:

podman run --rm -it -v ./:/work lscr.io/linuxserver/ffmpeg:8.1.2-cli-ls75 \
 -i /work/input.mkv -map 0:3 -c:a:0 libopus -b:a:0 256k -map 0:s? -c:s copy /work/test.mkv -y

podman run --rm -it -v ./:/work lscr.io/linuxserver/ffmpeg:8.1.2-cli-ls76 \
 -i /work/input.mkv -map 0:3 -c:a:0 libopus -b:a:0 256k -map 0:s? -c:s copy /work/test.mkv -y

Broken:

podman run --rm -it -v ./:/work lscr.io/linuxserver/ffmpeg:9.0-cli-ls77 \
 -i /work/input.mkv -map 0:3 -c:a:0 libopus -b:a:0 256k -map 0:s? -c:s copy /work/test.mkv -y
