AVCodec.hwp crash when mp4 video doesn't have audio stream

Post by AlexC »

I found that the AVCodec (64bit) plugin crashes if the video doesn't have an audio stream.
Using the native decoder, on some formats the player freezes too.

This is on windows 8.1pro
Using Hollywood 9.1
Making the videos in Blender 3.6.2
The formats I've tested and the result for each decoder:

; OpenVideo(1, "V:Videos/Tree5.avi") ; avi/mjpeg, native freezes, avc crash
; OpenVideo(1, "V:Videos/Tree5.mpg") ; mpeg1/2 native ok, avc crash
; OpenVideo(1, "V:Videos/Tree5vp9.webm") ; webm/vp9, native ok; avc not recognized
; OpenVideo(1, "V:Videos/Tree5png.mp4") ; mp4/png not recognized by either
; OpenVideo(1, "V:Videos/Tree5divx.mp4") ; mp4/divx both crash
; OpenVideo(1, "V:Videos/Tree5h264.mp4" ; mp4/h264 both crash
; OpenVideo(1, "V:Videos/Tree5.ogv") ; ogg/theora native ok, avc not recognized, ogg plugin crash
; OpenVideo(1, "V:Videos/Tree5av1.mp4") ; mp4/av1 not recognized by either
; OpenVideo(1, "V:Videos/Tree5mp4.mkv") ; mkv/mp4, native ok, avc crash
; OpenVideo(1, "V:Videos/Tree5h264.mkv") ; mkv/h264, native plays but shrinks video, avc not recognized
; OpenVideo(1, "V:Videos/Tree5yuv.mkv") ; mkv/yuv, native ok, avc not recognized
; OpenVideo(1, "V:Videos/Tree5na.mp4") ; mp4/h264 (no audio), native freeze, avc crash
OpenVideo(1, "V:Videos/Tree5a.mp4") ; mp4/h264 (w/AAC audio), native ends with blank frame, avc ok

Can you upload a sample video that crashes avcodec.hwp?

Sorry for the delay.
I couldn't find a way to upload a file with the reply so here's a link to download it (415kb)
