Yesterday, i got a crash with wavi.exe.

Since it seems that libvfw32.a was added to mingw-w64, I compiled wavi for 64bit.
wavi106m_x86_x64.zip note: I seldom use avisynth64. so, it is not often checking.

Sorry to revive this old thread but I can't get wav audio from an AVI made by an old Canon camera. Wavi is able to correctly determine the length of the audio but it can only write exactly one second of audio, which sounds perfect, before stopping.
Batch file is super simple as a test: wavi_x64 mvi_4522.avi test.wav pause Here's the MediaInfo report on the avi file: General Complete name : ...MVI_4522.AVI Format : AVI Format/Info : Audio Video Interleave File size : 343 MiB Duration : 3mn 2s Overall bit rate : 15.7 Mbps Mastered date : 2013-11-29 18:18:12 Writing application : CanonMVI06 Video ID : 0 Format : JPEG Codec ID : MJPG Duration : 3mn 2s Bit rate : 15.0 Mbps Width : 640 pixels Height : 480 pixels Original height : 960 pixels Display aspect ratio : 4:3 Frame rate : 30.000 fps Color space : YUV Chroma subsampling : 4:2:2 Bit depth : 8 bits Scan type : Interlaced Compression mode : Lossy Bits/(Pixel*Frame) : 1.629 Stream size : 327 MiB (95%) Audio ID : 1 Format : PCM Format settings, Endianness : Little Format settings, Sign : Signed Codec ID : 1 Duration : 3mn 2s Bit rate mode : Constant Bit rate : 705.6 Kbps Channel(s) : 1 channel Sampling rate : 44.1 KHz Bit depth : 16 bits Stream size : 15.4 MiB (4%) Alignment : Aligned on interleaves Interleave, duration : 1000 ms (29.99 video frames) Interleave, preload duration : 1000 ms Any suggestions? I'm guessing the problem has something to do with the interleave duration of exactly one second but then what? |

Some background on what I'm trying to do. I have 20-30 AVI files each in various folders. All are straight from my 2008 Canon camera which uses mjpeg and mono wav for its AVI files. I am trying to write a batch file to crawl through each folder and encode using X264, qaac, and mp4box. I know how to do this using avisynth but want to avoid that because I'd have to write 20-30 AVS files. (Unless there is a way to have them written automatically). My current batch file works fine using X264 on the AVIs but I can't extract the wavs for qaac to convert.
I'm getting close to extracting the audio using ffmpeg but not quite there yet. May try BeSweet next. Suggestions welcome. |

I don't use qaac, but for opus that would most likely be:
Code:
ffmpeg.exe -i "MVI_4522.AVI" -vn -f wav - | "opusenc.exe" --bitrate 64 --raw --raw-rate 44100 --raw-chan 1 - "MVI_4522.opus"
