System Information
Operating system: Arch Linux
Graphics card: GTX 970

Blender Version
Broken: 2.92 (Arch Linux package), but also manual 3.0 alpha (c154b078b5) build
Worked: 2.92 and 2.83.13 official binaries

Short description of error

I have a short video clip in Matroska format (see below for details). With the 2.92 and 2.83.13 official binaries creating a VSE proxy for this video works as expected. But with the Arch Linux 2.92 package and a locally built 3.0 alpha version VSE proxy generation fails:

The proxy_50.avi file is only a few kilobytes and subsequently the preview doesn't use the proxy
With 3.0 alpha the errors printed are Can't send video frame: Invalid argument, apparently coming from

static void add_to_proxy_output_ffmpeg(struct proxy_output_ctx *ctx, AVFrame *frame)
{
   ....

  int ret = avcodec_send_frame(ctx->c, frame);
  if (ret < 0) {
    /* Can't send frame to encoder. This shouldn't happen. */
    fprintf(stderr, "Can't send video frame: %s\n", av_err2str(ret));
    return;
  }

I suspect this is an issue related to the used FFmpeg version. As reported in system-info.txt these differ:

Official 2.92 binaries

FFmpeg:
=====================================

avcodec:   '58, 54, 100'
avdevice:  '58,  8, 100'
avformat:  '58, 29, 100'
avutil:    '56, 31, 100'
swscale:   ' 5,  5, 100'


Arch Linux 2.92 binaries, same for manually built 3.0 alpha:

FFmpeg:
=====================================

avcodec:   '58, 134, 100'
avdevice:  '58, 13, 100'
avformat:  '58, 76, 100'
avutil:    '56, 70, 100'
swscale:   ' 5,  9, 100'

Are there restrictions on which FFmpeg versions are used when building Blender? My current globally installed ffmpeg is 4.4.

Exact steps for others to reproduce the error

Add movie to VSE as strip, select it
Enable strip proxy & timecode
Set size to 50%
Set timecode index to Record Run
Rebuild proxy and Timecode indices
Console shows errors

Thx for the detailed report!

Indeed, this seems to be the same as #87932 (Failure to build movie strip proxy / ffmpeg incompatibility), will merge these reports.
