Description (last modified by cehoyos)

Remuxing an MKV with h264 video to an MPEG-TS (video only, audio doesn't matter) causes the video to freeze with latest FFmpeg builds.

The latest working build I have is N-43161-g31d8261 - a few days, or a couple of weeks after that, this issue came up.

It happens on my Sony Bravia TV, playing the same file remuxed using two different FFmpeg versions. The first output works, the second one freezes.

Works:

ffmpeg.exe -i "E:\remux_frozen_video_sample.mkv"  -y  -c:v copy  -map 0:0  -bsf h264_mp4toannexb   -c:a ac3_fixed  -b:a 640000  -ar 48000  -ac 6  -map 0:1  -f mpegts   -threads 0 -crf 23 "E:\out.mts"

I've tried both w32threads and pthreads without luck.

I'm uploading a sample "remux_frozen_video_sample.*" to the ftp.

comment:1 Changed 5 years ago by rogerdpack

what about other players? It might be hard to reproduce the failure if devs need a Sony bravia...

comment:2 Changed 5 years ago by dvlpr

I'll need to check, but I think VLC plays it fine. It may be some change that makes the file less-compatible with hardware-based players.

comment:3 Changed 5 years ago by cehoyos

  • Description modified (diff)

comment:4 Changed 5 years ago by cehoyos

  • Component changed from undetermined to avformat
  • Keywords regression added
  • Priority changed from normal to important
  • Status changed from new to open
  • Version changed from unspecified to git-master

I suspect this is a regression since 3e1cf49 - related to ticket #1242.

comment:5 Changed 5 years ago by michael

Please find / confirm the exact git revission at which this problem was introduced.
Especially if this cannot be reproduced with a software player that we have access to.

comment:6 Changed 5 years ago by dvlpr

With Carl's help, I can confirm that git 2107009 works and 3e1cf49 fails.
