Description

Using FFmpeg 4.1.4 32 and 64 bits tools.

  • 64 bits tool seems to encode broken Theora video. Bad video and many errors shown with FFplay.
  • 32 bits tool works as expected. Good results and no errors shown in FFplay.

Many input video types has been tested and all of them show problems. The command to test is:

ffmpeg -i in.mp4 -t 5 -c:v theora -q:v 5 out.ogv

Choppy playing and pixelated blocks in most cases. The errors shown in FFplay are like this:

ffplay -report output64.ogv

Please test current FFmpeg git head and provide the ffmpeg command line you tested together with the complete, uncut console output to make this a valid ticket.

I assumed last Zeranoe 64 bit nightly build (which I used for my tests) were up to date but after building FFmpeg git head by myself I've verified that Theora encoding is working. Thanks for your hint and time.
