No Title/Subtitle on files manually transcoded to PSP format

[johnnyb]

Problem existed on 98.13 and on current 99.05

Yes I know it's only a minor bug.... but using the Transcode option from the video library to convert mpg files to PSP mp4 format does code the title and subtitle into the file. Since it is this information which is displayed on the PSP, it makes selecting which program to watch fairly difficult - all programs are listed as 'title - subtitle'.

This works OK for those files automatically converted.

Anyone know of a way to manually add this info into an mp4 file. Can't seem to find tool to display or edit this info.

I think its just a limit in the program gbpvr calls to transcode the video. I guess it just converts to MP4 rather than PSP compliant MP4.

One for the wishlist maybe cos I agree it would be most useful....

Hi Fuzzweed,

ffmpeg can add the info....... I autoconvert all my recordings to PSP format (using the autoconvert settings on 'processing' tab on gbpvr config) and ffmpeg does add the title/subtitle to the mp4 files. I am now converting some of my old recordings manually, but title/subtitle do not get added.

Would be nice to fix.

It only knows the title/subtitle when you let GB-PVR automatically as it recordings. When you do it from the Video Library, it's just any old file, so none of this extra info is known. The video library knows nothing about recordings.

Thanks sub. That explains it.

Thanks sub. That explains it.

Johnnyb, if you're interested in some trial and error, I won't mind writing this into ZProcess, which is a sort of go-between frontend for ffmpeg, which is the default transcoder used by GB-PVR. As sub said, when you manually transcode a file in the Video panel, ffmpeg is unable to know the title, subtitle. But it does know that info when passing the information to the PostProcessing.bat for an auto transcode.

Anyway, what I propose is, starting ZProcess from your desktop, selecting a file to transcode, selecting a PSP profile, and being asked at that time what Title and Subtitle you wish to use.

Currently there would be no way to launch ZProcess with this type of interaction inside GB-PVR unless I build a plugin/skin.

As I don't have a PSP, I have been unable to work on that feature...

Thanks zehd. I am willing to try this. I haven't used ZProcess but have seen it mentioned in the forums. All the files I am converting are old gbpvr recordings, so they have program info in metadata stream of the mpeg file. Is there any way to pick up this info automatically?

I will have a look on the wiki to see what zprocess does etc.

just figured out a work around for titling PSP videos from a manual transcode. Add another transcoding option to config.xml:

<Conversion name="Sony PSP manual" cmd="-y -i {SOURCE_FILE} -title {SOURCE_FILE} -f psp -r 29.97 -s 368x208 -b 768k -ar 24000 -ab 64 {DEST_FILE}" targetExtension=".MP4" />

then the PSP video gets titled with the path of the original vid e.g d:\my videos\video.avi

not perfect but it does at least let you see whats there.
