    Im trying to use the external encoder for virtualdub but it keeps hanging at the end of the render saying possible live lock.

    I simply need it to encode an avi to mp4 ready to upload to youtube.

    This is the code:

    Code:
    {
    	"description": "VirtualDub external encoder profile collection",
    	"externalEncoders": {
    		"sets": {			
    			"AVI to YouTube": {
    				"videoEncoder": "FFmpeg Video",
    				"audioEncoder": "FFmpeg AAC-LC",
    				"multiplexer": "FFmpeg Multiplexer",
    				"description": "(name.mp4 - video + audio)",
    				"extension": "mp4",
    				"processPartial": false,
    				"useOutputAsTemp": false
    			}
    		},
    		"profiles": {
    			"FFmpeg Video": {
    				"name": "FFmpeg Video Encoder",
    				"program": "C:\\Encoders\\ffmpeg\\ffmpeg.exe",
    				"commandArguments": "-f rawvideo -s %(width)x%(height) -r %(fpsnum)/%(fpsden) -i - -c:v libx264 -preset slow -profile:v high -crf 18 -coder 1 -pix_fmt yuv420p -movflags +faststart -g 30 -bf 2 \"%(tempvideofile)\"",
    				"outputFilename": "%(outputname).264",
    				"type": 0,
    				"inputFormat": 0,
    				"checkReturnCode": true,
    				"logStdout": true,
    				"logStderr": false,
    				"bypassCompression": false,
    				"predeleteOutputFile": false
    			},
    			"FFmpeg AAC-LC": {
    				"name": "FFmpeg Audio",
    				"program": "C:\\Encoders\\ffmpeg\\ffmpeg.exe",
    				"commandArguments": "-i - -c:a aac -b:a 384k -profile:a aac_low \"%(tempaudiofile)\"",
    				"outputFilename": "%(outputname).aac",
    				"type": 1,
    				"inputFormat": 1,
    				"checkReturnCode": true,
    				"logStdout": true,
    				"logStderr": true,
    				"bypassCompression": false,
    				"predeleteOutputFile": false
    			},
    			"FFmpeg Multiplexer": {
    				"name": "FFMpeg Multuplex",
    				"program": "C:\\Encoders\\ffmpeg\\ffmpeg.exe",
    				"commandArguments": "-i \"%(tempvideofile)\" -i \"%(tempaudiofile)\" -map 0 -map 1 -c copy -f mp4 -y",
    				"outputFilename": "%(outputname).mp4",
    				"type": 2,
    				"inputFormat": 0,
    				"checkReturnCode": true,
    				"logStdout": true,
    				"logStderr": true,
    				"bypassCompression": false,
    				"predeleteOutputFile": false
    			}
    		}
    	}
    }
    3 files are created called:
    • test.mp4.264
    • test.mp4.aac
    • test.mp4

    The progress bar sits at 100%, the Log says:

    Dub: Processing thread not cycled for thirty seconds - possible livelock
    And I have to quit VirtualDub as its hung.

    Help appreciated!

  2. Does this happen with every input file? What input file driver are you using? Is the source an AviSynth script?

    I see one of your temp files is called "test.mp4.264" (i.e. .264 file extension). Since you haven't forced mp4 output using -f either the temp video file will not be mp4 container but H.264 elementary stream. This will eventually lead to a broken output file since ffmpeg doesn't mux the latter correctly to mp4.

    Yeah any avi file. The source is whatevers loaded in virtualdub. I havent used ffmpeg before so not entirely sure about the commands im using. Ill try adding the -f to the video command. Do i need to add it to the audio one too?

  4. It's "-f mp4" for mp4 format forcing. Also add "-y" to every command to make sure it overwrites existing files. And post the complete VirtualDub log, not just the last line.

    Ok. Added those commands but still same issue:

    			}
    		}
    	}
    }
    Attached the log as well.

    Thanks.

  6. you can also try vdub2 - it can export using x264 / aac / mp4 directly without the external encoder feature

    In the external encoder video settings activate "redirect standard error to log", then run and post log again.

    How long is the source video? Only 7 seconds? Does the encode finish if you cut it to 6 seconds?

    Im just selecting a part of the timeline for testing as its about 50 minutes long!

    Have attached log with "redirect standard error to log" for video:

    Also tried it in vdub2 as suggested by poisondeathray. I know vdub2 exports mp4 but I'd rather the external encoder working as well.

    There's a bit more detail on the error which might give clues:

    And the log file is attached.

  10. You are missing "%(outputname)" from the muxer settings.

    @sneaker: I tried your fix but it still does same thing. See log from normal virtualdub:

    Edit: Seems to work on vdub2 though :/

  12. I reuploaded the fix. Try again with VirtualDub2. It should fix the "CLI: multiplexing failed with ...." message. It will not fix the livelock you have with the old VirtualDub. That seems to be a deeper problem and is not because of wrong settings. Maybe it's a problem with the input drivers or VfW/ACM codecs.

    Thanks sneaker. Yes, it sounds like an issue with VirtualDub itself. Wish Id known that before bashing head on desk over it!
