Hi list,
This is one of the first time I attempt to read video in Gem. I must have done bad things in my life before : nothing works...
I have dv exports from a camera : when I try to read them as they are, pd just crashes (terminal output at the end of mail).
So I tried to re-encode them but I seem to get the same error with every codec that doesn't crash Gem immediately :
mpeg3video_seek: frame accurate seeking without a table of contents is no longer supported. Use mpeg3toc <mpeg file> <table of contents> to generate a table of contents and load the table of contents instead.
Then Gem kind of reads the video (sometimes faster, sometimes normal) but when I load a second one, it usually freezes the whole pd process...
By the way : transcode doesn't seem to be very stable in Ubuntu (many segfaults).
Someone has a tip, a failsafe solution ? I just want to read those video files... (:
Thanks in advance folks.

hi jerome,
you can try my videos: http://www.workinprogress.ca/pd/gem/
but the xvid are not working (it's loading but the cpu don't like it). i sent an email on gem-dev asking if someone could take a look. also, know that transcode version on gutsy is too old, you need to compile it from source. as an alternation, ffmpeg, mencoder are good too.
just to be sure it's not just on my box, anyone can test XVID with gem. what's you cpu usage compare to mplayer, ffplay, aviplay?

Hi list,
This is one of the first time I attempt to read video in Gem. I must have done bad things in my life before : nothing works...
I have dv exports from a camera : when I try to read them as they are, pd just crashes (terminal output at the end of mail).
So I tried to re-encode them but I seem to get the same error with every codec that doesn't crash Gem immediately :
mpeg3video_seek: frame accurate seeking without a table of contents is no longer supported. Use mpeg3toc <mpeg file> <table of contents> to generate a table of contents and load the table of contents instead.
Then Gem kind of reads the video (sometimes faster, sometimes normal) but when I load a second one, it usually freezes the whole pd process...
By the way : transcode doesn't seem to be very stable in Ubuntu (many segfaults).
Someone has a tip, a failsafe solution ? I just want to read those video files... (:
Thanks in advance folks.

Jé

hi jerome,
you can try my videos: http://www.workinprogress.ca/pd/gem/
but the xvid are not working (it's loading but the cpu don't like it). i sent an email on gem-dev asking if someone could take a look. also, know that transcode version on gutsy is too old, you need to compile it from source. as an alternation, ffmpeg, mencoder are good too.
just to be sure it's not just on my box, anyone can test XVID with gem. what's you cpu usage compare to mplayer, ffplay, aviplay?
patrick
both of them don't play in gem. i can load them, but they play very slow and a major part of the image is just coloured garbage.
i am not sure, if i understand why you want to get xvid working with gem. if you are interested in lowest possible cpu consumption, i wouldn't expect xvid to give the best results, since it is optimized to give very high compression and not to consume as little cpu as possible. you said in another post, that you used a flag '-intra' wich turns every frame into a keyframe. xvid is a codec, that is able to produce mpeg4/ASP compliant video files. it is the nature of divx (and all mpeg4/ASP codecs) to use interframe compression, which means: only update parts of the image, that have changed. i don't quite see the point of using xvid, when forcing intraframe compression (every frame compressed seperately, without depending on previous [or even coming, as used in some advanced codecs] frames).
i haven't tested extensively myself, but there are some codecs around, that do intraframe compression natively: dv/photo-jpeg/mjpeg/jpeg. don't ask me about the details and differences between these codecs, but they have in common, that they are designed to access arbitrary frames randomly. some of them are probably optimized for good image quality (dv), others probably for low cpu-consumption. if cpu load is the main factor you are interested to optimize, try on of these, i'd suggest.
probably some people with better knowledge (devs?) can shed light on this, but i suspect, that the decoding might not be the major reason, why gem uses so high cpu load, when displaying a video, but probably the transport of the data. aaik, mplayer is highly optimized in that respect, so if using a fast output as -vo xv, almost all cpu cycles are used for decompression, neither for displaying nor for transport. -vo gl eats 60% (50% @ 600MHz) more cpu than -vo xv (31% @ 600MHz). so displaying through opengl (what gem does as well) seems to add some overhead.

after testing many codec on linux, XVID is the best codec for filesize and cpu. both. playing a dv, jpeg quicktime or mjpeg avi are +- 35% of my cpu (640x480 / 30 fps). XVID will take only 7% of my cpu and the filesize is reduced by half. by forcing keyframe every frame i can (in theory) use it like jpeg, mjpep (skip, scratch etc...).

right! decoding a quicktime jpeg in gem or in mplayer -vo gl is the same cpu consumption. but there's a problem with xvid decoding mechanism.
i filled a bug report in sourceforge. pat
Hrm. Thats pretty interesting - and I honestly would not have
suspected this to be the case - in my tests on OS X, mjpeg has
consistently been the winner. My understanding reflects romans earlier
posts to a t.
Can you put/host the videos anywhere? How were you compressing the
Quicktime files and the XVIDs?

hi vade,
on linux using transcode, but sometimes ffmpeg or mencoder.
examples:
quicktime - jpeg (4.0M) http://www.workinprogress.ca/pd/gem/codec/out_jpeg.mov
gem 22% cpu - showing the video gem 17% cpu - just decoding the video mplayer xv 5% cpu mplayer gl 9% cpu
transcode -i dvd.vob -c 500-1000 -y mov,null -F jpeg,,jpeg_quality=70 -G 1.1 --pre_clip 6,18,6,18 -J denoise3d=2,pp=lb -Z 640x480 --zoom_filter Mitchell -o out_jpeg.mov
avi - mjpeg (4.1M) http://www.workinprogress.ca/pd/gem/codec/out_mjpeg.avi
gem 19% cpu - showing the video gem 14% cpu - just decoding the video mplayer xv 5% cpu mplayer gl 9% cpu transcode -i dvd.vob -c 500-1000 -y ffmpeg,null -F mjpeg -G 1.1 --pre_clip 6,18,6,18 -J denoise3d=2,pp=lb -Z 640x480 --zoom_filter Mitchell -o out_mjpeg.avi
avi - xvid (933K) http://www.workinprogress.ca/pd/gem/codec/out_xvid.avi
gem 90% cpu - just decoding the video mplayer xv 3% cpu mplayer gl 7% cpu transcode -i dvd.vob -c 500-1000 -y ffmpeg,null -F xvid -G 1.1 --pre_clip 6,18,6,18 -J denoise3d=2,pp=lb -Z 640x480 --zoom_filter Mitchell -o out_xvid.avi
ffmpeg / mpeg4 (977K) http://www.workinprogress.ca/pd/gem/codec/out_mpeg4.avi
gem 90% cpu - just decoding the video mplayer xv 3% cpu mplayer gl 7% cpu transcode -i dvd.vob -c 500-1000 -y ffmpeg,null -F mpeg4 -G 1.1 --pre_clip 6,18,6,18 -J denoise3d=2,pp=lb -Z 640x480 --zoom_filter Mitchell -o out_mpeg4.avi
i tested some mpeg2video, but since gem is crashing when loading the .toc file i cannot know if there's more consumption of cpu in gem vs mplayer / ffplay etc...
maybe there's another codec to try? patrick

this is interesting. i get similar results here:
http://www.workinprogress.ca/pd/gem/xvid.avi -> mplayer uses approximately 4.3% cpu @ 1.7GHz
mov, mjpeg with 640x480 @ 30fps -> mplayer uses approximately 7.5% cpu @ 1.7GHz
your xvid with -intra is faster, which is interesting.
the question remains, how much of the processing power is used to decode the stream and how much is used for transport and displaying in gem.
since i cannot play your xvid.avi file, i cannot make the same comparison in gem.
