1857608 - GBR-planar WebM vp9 video won't play on Android

Status: NEW

(Core :: Audio/Video, enhancement)

Description

[Matthias Braun]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:109.0) Gecko/20100101 Firefox/118.0

Steps to reproduce:

Try to play this video in Firefox 113:

https://mb.sb/teaching/networking/internet/videos/globe_crf_55_720.webm

Actual results:

The browser shows a message: "Video can't be played because the file is corrupt"

Expected results:

I expected the video to play.

It does play in:

• Firefox 118.0.1 on Linux
• Chromium on Linux
• Vanadium on GrapheneOS
• Samsung Internet on Android

---

The WebM video in question was created from a set of PNGs using

ffmpeg -i %03d.png -vf scale=720:720 -crf 55 globe_crf_55_720.webm

If I convert the video using

ffmpeg -i globe_crf_55_720.webm -pix_fmt yuv420p globe_crf_55_720_yuv420p.webm

the resulting video plays in Firefox on Android: https://mb.sb/teaching/networking/internet/videos/globe_crf_55_720_yuv420p.webm

Maybe this issue is related to that: https://bugzilla.mozilla.org/show_bug.cgi?id=1368063

I originally created a bug report for this issue here: https://gitlab.com/relan/fennecbuild/-/issues/55

Can you take a look?

[Makoto Kato [:m_kato]]

I can reproduce this with https://mb.sb/teaching/networking/internet/videos/globe_crf_55_720.webm on Android 14 + Pixel 6a. Firefox Nightly the lastest version cannot play this WebM correctly.

I think the most suspicious part is SoftVPX : frameworks/av/media/libstagefright/codecs/on2/dec/SoftVPX.cpp:142 CHECK_EQ( mImg->fmt,VPX_IMG_FMT_I420) failed: 262 vs. 258
262 -> 0x106 -> VPX_IMG_FMT_I444
258 -> 0x102 -> VPX_IMG_FMT_I420

So maybe the android's vpx library cannot handle format VPX_IMG_FMT_I444

From ffmpeg:
https://github.com/FFmpeg/FFmpeg/blob/master/libavcodec/libvpxenc.c#L814-L819 AV_PIX_FMT_GBRP will use VPX_IMG_FMT_I444 as img_fmt (in the switch statement fall-through)

On Pixel 6 + Android 13 , the video does not show message "Video can't be played because the file is corrupt", just jump to the end of video with all black.

adb log:

10-07 20:20:13.762 8096 16097 I CCodecConfig: query failed after returning 17 values (BAD_INDEX)

then endless loop of:

10-07 20:20:15.232 830 16098 W ExynosC2Vp9DecComponent: [onUpdateC2Work] input is corrupted
10-07 20:20:15.234 830 16099 E libexynosv4l2: failed to ioctl: VIDIOC_G_FMT (11 - Try again)

[Karl Tomlinson (:karlt)]

Bug 1368063 comment 4 indicates an expectation that this should play, given the free codec.
