Reproduction Steps

curl 'https://download.blender.org/peach/bigbuckbunny_movies/big_buck_bunny_480p_h264.mov' > bbb1.mov
cp bbb1.mov bbb2.mov
mpv 'edl://bbb1.mov,0,10;bbb2.mov,0,10' --no-config --vd-queue-enable

Then wait 10 seconds, or attempt to seek past the 10 second mark.

Note that as long as the timeline stays within the first file, for example with edl://bbb1.mov,0,10;bbb1.mov,0,10, the player functions as expected.

Matroska ordered chapters cause the same problem.

Expected Behavior

The EDL is respected; in the example, the first 10 seconds of bbb1.mov are played before the first 10 seconds of bbb2.mov, then playback finishes.

Actual Behavior

The video hangs at the point where the EDL references a different file (in the example, at 10 seconds), audio continues playing. After attempting to seek beyond the 10 second mark, the player does not respond to any input, not even SIGTERM, I need to close it with killall -9 mpv.

Log File

I attempted to seek backwards after 29.797s of starting the player.

Sample Files

(see Reproduction Steps)

I carefully read all instruction and confirm that I did the following:

• I tested with the latest mpv version to validate that the issue is not already fixed.
• I provided all required information including system and mpv version.
• I produced the log file with the exact same set of files, parameters, and conditions used in "Reproduction Steps", with the addition of --log-file=output.txt.
• I produced the log file while the behaviors described in "Actual Behavior" were actively observed.
• I attached the full, untruncated log file.
• I attached the backtrace in the case of a crash.
