Cor Posted October 17, 2017 Share Posted October 17, 2017 Hi, I'm having issues with my JAMME capture files. I have issues both with avi capturing and pipe capturing, but totally different issues.I'll start with pipe, as it is what I would prefer to capture with. Pipe I have no issue per say with the file itself, the problem is bringing that file into an editing program. The program will recognize the audio but not the video (I've tried 3 different major programs). By searching on the net, it seems to probably be caused by the codec or the encoding of the video file. Anyway, apparently, no way to really get around that, so would it be possible to change the capture settings of pipe to something else... I'm referring to that line in jampconfig.cfg: seta mme_pipeCommand "ffmpeg -f avi -i - -threads 0 -preset ultrafast -y -pix_fmt yuv444p -crf 23 %o.mp4 2> ffmpeglog.txt" Don't ask me to explain any of that, this is just the default configuration. Could I change a few settings to end up with another "type" of video file?My current solution is converting the file with "Handbrake" which allows for lossless conversion, the file can then be viewed in the editing software. But deleting that step would be good. Note: I've tried installing a few different codecs suggested on the web but none worked. Now onto the avi files... .avi Then again, I could say that there is no REAL issue, as I can "watch" the files, bring them into an editing program, extract them out of the program in a more compressed version (ready for youtube) and from this point, the videos can be watched perfectly. But before extracting the videos out of the editing program, I can't actually watch them properly, as the files are buggy: they freeze a little (or a lot) and I can't get 1 second of fluidity. You could think that this isn't such a big deal as they become fine once extracted, but I will be doing a lot of editing within the editing program and not being able to watch the video plays out normally makes it nearly impossible for me to do that. I've tried capturing in 30FPS and 60FPS and I've set aviformat to 1 (and 0). I also capture in 1920x1080. Has anyone experienced this with avi capturing? Thx for any help you could give me.

ent Posted October 17, 2017 Share Posted October 17, 2017 Hi.seta mme_pipeCommand "ffmpeg -f avi -i - -threads 0 -preset ultrafast -y -pix_fmt yuv444p -crf 23 %o.mp4 2> ffmpeglog.txt"Try -pix_fmt yuv420p. Blame Apple for that.PotPlayer can play yuv 444 (I think it uses ffmpeg on backend).Sony Vegas cannot play yuv 444 back though.I've already changed the default value to yuv420p and it will be like that in a new version: https://github.com/entdark/jaMME/commit/7c0f86fe5a9ac5a9029656ca5cede5c8c9d2c9bf#diff-08ef480c53ed0cc5fabaddc9a374322d Could I change a few settings to end up with another "type" of video file?Yes, you can change everything after "ffmpeg -f avi -i -".Read more about that in https://jkhub.org/topic/8156-jamme-110-released/ I can't actually watch them properly, as the files are buggy: they freeze a little (or a lot) and I can't get 1 second of fluidity.I guess you capture uncompressed avi, so the bitrate is too high to handle it without lags in any player with modern hardware.1920x1080x30x3 (3 color channels per pixel, each channel is 1 byte) = 186624000 bytes / sec = 186 MB / sec.Should be better with mme_avifromat 1 since it compressed frames with JPG. But anyways try pipeline first, it should fix that. Link to comment
Cor Posted October 17, 2017 Author Share Posted October 17, 2017 Changing "444p" to "420p" worked, no more need of conversion... thank you very much!As for the avi files, I had tried to set mme_aviformat to 1 before but no luck... Although, recording an avi file with aviformat 1 and 30FPS results in a less buggy file, but still buggy. I have also tried since I made this post to use savewav 1, but no luck there again. As for now though, I can record in pipe, so that will do. Link to comment
