[Question] Seeking

[VampiricAlien]

Sometimes I can only watch from the beginning and can’t seek through the video, if I do it starts at the beginning again.

Do you know why or how this would happen? creating a new file fixes the issue.

[mdhiggins]

Not really enough info to help

I assume the original file that's failing is created with SMA and also creating a new file with SMA fixes it?

Only time I've seen seeking issues is when trying to tag/add metadata AFTER qtfaststart or equivalent MOOV atom has been moved which if you're doing MKV doesn't apply

[VampiricAlien]

The new file is created with ffmpeg without the script. H.264 --> H.265 creates a new file but on some media the seek was broken but fixed by using ffmpeg copy command.

Is there any options to check this?

[mdhiggins]

Check what?

I would maybe need to see some conversion logs from a file that's broken and perhaps send me a sample file that's not seeking

[VampiricAlien]

To check video time or seek?

I think I do have a log but I no longer have those files.

[mdhiggins]

I don't think there's a programmatic way to see if this has occurred if that's what you're asking, but that's tough to say without seeing if there was some problem or error during the conversion process or looking to see if the file is malformed in some way. Usually its a problem with the wrapper and that's why recreating it using FFMPEG copy fixes things but if you have some logs I can take a look and see if anything stands out

[VampiricAlien]

This is what I could find in the logs

[mdhiggins]

Everything looks to be proceeding without any major issues (other than the cleanit error which is irrelevant)

I'm curious maybe if you try turning off tagging if that makes any impact but otherwise looks like an appropriate FFMPEG command is generated

Are you seeing this with every file or was it just a specific one?

Also I did just double check the latest cleanit version and that import error you're getting shouldn't be there so you might want to update/reinstall cleanit to fix that

[VampiricAlien]

That was my thoughts, nothing stood out to me in the log. It is very rare that it happens.

I did keep this bit of info from the file before fixing it. It's not a big deal since it doesn't happen a lot.

[VampiricAlien]

Off topic question before I close this.

How would i get the script to copy 'h265 yuv420p' video stream when it's not supported by my vaapi? the setting is 'h265 p010le' I took me awhile to pin point the error linked to pix-fmt, any ideas?

[mdhiggins]

It will always remux a stream even with hardware acceleration if the stream doesn't break any rules so just add make sure to add the codec and pixfmt to the lists

[VampiricAlien]

If I add that to the list I get this error

No usable encoding profile found. [vost#0:0/hevc_vaapi @ 0x55a5d086f000] Error initializing output stream: Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height Conversion failed!

Is there another way to make sure all 265 video streams get copied?

[mdhiggins]

Share your config it shouldn't be your first option. Please review in the wiki

[VampiricAlien]

[Video]
codec = h265vaapi
max-bitrate = 0
bitrate-ratio = 0.7
max-width = 0
preopts = -extra_hw_frames, 10
crf = -0
preset = veryslow
codec-parameters = 
dynamic-parameters = True
profile = main10
max-level = 5.2
pix-fmt = p010le, yuv420p10le
prioritize-source-pix-fmt = True
filter = 
force-filter = False
crf-profiles = 

pix-fmt csv Supported pix-fmt list. Formats not on this list are be converted to the first format on the list

prioritize-source-pix-fmt bool True When decided pix_fmt, the script will attempt to keep the same format as long as it's included on the allowed list if video conversion must take place, set to False to use the first pix_fmt on the list instead if conversion must take place (will not impact conversion needed decisions)

[mdhiggins]

If you're getting the error above that means its still not copying, the "debug" tag on the json data usually tells you why its not getting copied

Depending on your specific needs you can also potentially just leave pix_fmt blank

IO... p010le                 3             15      10-10-10

p010le isn't a hardware accelerated format so that shouldn't be your first choice since you're trying to use VAAPI

ffmpeg -pix_fmts will give you a list of your ffmpeg builds supported pix_fmts

You'll also probably need to play around with prioritize-source-pix-fmt = True as it might need to be set to false in situations where you need to convert

[mdhiggins]

Sharing the full logs would be helpful too

[VampiricAlien]

Drop 10 from main and changed other settings like you suggested, it now copies over. As for ffmpeg -pix_fmts didn't really give anything to use for hardware.

profile = main max-level = 5.2 pix-fmt = nv12, p010le, yuv420p10le, yuv420p prioritize-source-pix-fmt = False

I can make a suggestion?

Within the wiki, having a little area for tips and tricks or FAQs.

Thank you for the help.
