Error when saving the video in arrays

[sumwor]

Hi I encountered the error when loading the raw video and save it in arrays

varr = save_minian( varr.chunk({"frame": chk["frame"], "height": -1, "width": -1}).rename("varr"), intpath, overwrite=True, )

Here is the output in the console:
Input #0, avi, from 'Z:\miniscope.avi': Metadata: software : Lavf55.12.100 Duration: 00:01:05.10, start: 0.000000, bitrate: 11537 kb/s Stream #0:0: Video: mpeg4 (Simple Profile) (FMP4 / 0x34504D46), yuv420p, 1440x1440 [SAR 1:1 DAR 1:1], 11536 kb/s, 30 fps, 30 tbr, 30 tbn Stream mapping: Stream #0:0 -> #0:0 (mpeg4 (native) -> rawvideo (native)) Press [q] to stop, [?] for help Output #0, rawvideo, to 'pipe:': Metadata: software : Lavf55.12.100 encoder : Lavf60.16.100 Stream #0:0: Video: rawvideo (Y800 / 0x30303859), gray(pc, progressive), 1440x1440 [SAR 1:1 DAR 1:1], q=2-31, 497664 kb/s, 30 fps, 30 tbn Metadata: encoder : Lavc60.31.102 rawvideo [vost#0:0/rawvideo @ 0000016976296C00] Error submitting a packet to the muxer: Broken pipe2.35x [out#0/rawvideo @ 000001697623D900] Error muxing a packet [out#0/rawvideo @ 000001697623D900] Error writing trailer: Broken pipe [out#0/rawvideo @ 000001697623D900] Error closing file: Broken pipe [out#0/rawvideo @ 000001697623D900] video:2640600kB audio:0kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead: unknown frame= 1304 fps= 70 q=-0.0 Lsize= 2639983kB time=00:00:43.80 bitrate=493761.2kbits/s speed=2.34x Conversion failed!

I have had no problem running the same command on another video I took with miniscope software. The video with issue were taken using Bonsai miniscope package. Therefore I suspect that it has something to do with video encoding and/or header. I really appreciate the help. Thank you!

Hi! Is the video you're trying to upload named 'miniscope.avi'?

In the beginning stages of the pipeline, there is a dictionary where you can change the name of the file that Minian will be looking for:

# Pre-processing Parameters#
param_load_videos = {
    "pattern": "msCam[0-9]+\.avi$",
    "dtype": np.uint8,
    "downsample": dict(frame=1, height=1, width=1),
    "downsample_strategy": "subset",
}

The key "pattern" is what you would want to change so that Minian can recognize your raw video. In this case, if this is the only video in your folder that you need to analyze, you can change it to:

param_load_videos = {"pattern": "miniscope.avi" ... }

Let me know if this is something you've already changed or if the .avi files you're uploading are different!
