Error initializing output stream: Error while opening encoder for output stream #0:0

Just upgraded to Sonoma. Made sure i Updated Homebrew, all packages, and OVT was the latest. (Running on a Mac Book Pro M1 Max).

However, when I run my usual command:

other-transcode --vt-allow-sw --mp4 --hevc --crop 0:0:68:68 '/Users/ravedog/Desktop/rips/The Holdovers (2023)/src/ds-Road Back to Barton.mkv'

I am now met with an error:

Error initializing output stream: Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height /usr/local/bin/other-transcode: transcoding failed: ds-Road Back to Barton.mp4

If I remove --hevc it will work. These are the same MKV source files that worked prior to updating my MacOS.

Here is the generated log file:

Any ideas?

skj-dev commented

I don't know what the specific problem is, but there are two things I'd try first.

  • Update to ffmpeg 6.1.1 (this was released recently ... it might not make any difference, but my default tends to be to first update to the latest version if there is a problem)
  • Remove the --vt-allow-sw option. I'm not implying that's the problem, but that's a special option, so I typically try to remove elements like that when troubleshooting.

Also, it's possible that this is a source file problem. To that end, it might be useful to try the same command on a different (ideally, a "known good") source file.

ravedoglv commented

i undated ffmpeg but still the same issue. However, removing --vt-allow-sw seems to fix it. However it is not using hardware acceleration now.

skj-dev commented

That's certainly odd, especially since I would expect removing the flag to allow software encoding to ensure that the Video Toolbox encoder would be used.

When you remove the -vt-allow-sw flag does other-transcode use x265 as opposed to hevc_videotoolbox?

And of course, it could still be a source file issue. The only reason I bring that back up is because sometimes weirdness in a source file can cause all kinds of issues that others haven't seem and/or is hard to reproduce.

ravedoglv commented

I was wondering of there were any follow up ideas how to enable hardware acceleration. Also, The source files - i tried some older ones that used to work and they have an issue now. So i think i can rule out the media.

Hi there! No idea how much help I can be but let's try a few things, and others may chime in as well.

  • Can you paste the ffmpeg command line that's generated when you don't use the --vt-allow-sw option?
  • If you remove the HEVC flag from other-transcode, does it properly use VT hardware acceleration for H.264 output?
  • If the answer is "yes" to the second question, try the HEVC command again while removing all other options (i.e., don't crop, use default MKV output rather than MP4, etc. Only other-transcode --hevc [file].

Let us know how that goes!

is the ffmpeg command issued without the --vt-allow-sw option

if i remove the --hvec option it transcodes with acceleration, yes:
ffmpeg -loglevel error -stats -i /Users/ravedog/Desktop/rips/Lone\ Star\ \(1996\)/src/Interview\ with\ Dryburgh\ DP.mkv -map 0:0 -filter:v crop\=1696:1050:180:30 -c:v h264_videotoolbox -b:v 6000k -allow_sw:v 1 -color_primaries:v bt709 -color_trc:v bt709 -colorspace:v bt709 -metadata:s:v title\= -disposition:v default -map 0:1 -c:a:0 copy -metadata:s:a:0 title\= -disposition:a:0 default -sn -metadata:g title\= -movflags disable_chpl Interview\ with\ Dryburgh\ DP.mp4

if issue the command other-transcode --vt-allow-sw --hevc /Users/ravedog/Desktop/rips/Lone Star (1996)/src/Conversations with Sayles & Sava.mkv without the --mp4 option it errors:

i get an error Error while filtering: Generic error in an external library [out#0/matroska @ 0x7f955bf046c0] Nothing was written into output file, because at least one of its streams received no packets.

So it will work with acceleration if I dont use --hvec and it transcodes with H.264

skj-dev commented

That is very odd. Does other-transcode not "find" the hevc_videotoolbox encoder? The --hevc option should try (and use) that, but it looks like it's defaulting to software encoding for you for some unexplained reason.

For example:

❯ other-transcode --hevc src/foo.mkv --dry-run

In my case, these are the versions I'm using on a Mac Studio:

  • ffmpeg version 6.1.1 (this is actually one I build, but that shouldn't make any real difference ... https://git.skj.dev/sean/macOS-ffmpeg/releases)
  • ffprobe (same as above)
  • mkvpropedit v82.0 ('I'm The President') 64-bit
  • other-transcode 0.12.0
