Image (jpg/png) to video with avidemux 2.7 dev branch

[Jan Gruuthuse]

I've come across some issues while revisiting the PNG to video transfer, ubuntu 16.04.2 LTS Qt5
Seems to be working only with Display: Xvideo(best) with Video Output (xvid4) and Output format: Mkv Muxer
however there looks like to be a timeline issue with markers?
While pasting the image A: and B: counters increase each with 00:00:040, causing probably the to short message?

Workflow:
- load one 1280x720 pixels jpg or png
- copy and paste up to 500 ms
Video Output (xvid4)
Output format: Mkv Muxer
save video: too Short .... incomplete
set slider begin mark [A ], save : too Short .... incomplete
set slider end mark [ B], save : done

I could not save video with
- Mpeg4 AVC (x264)
- Mpeg4 ASP (ff)

Download link https://we.tl/H6woEyLDGX 1 file TestImageToVideo.zip, 61.8 MB in total ãÆ'» Will be deleted on 28 July, 2017
contents: one jpg + png 1280x720 pxls, 3sat test 720p video

Time permitting, could be looked at this?

Further testing after finding time line issue
image to video working on Display & HW accel: vdpau
- (FF)HuffYUV
- HEVc (x265)
- Mjpeg Encoder
- Mpeg4 ASP (xvid4)
- Nvidia H264
- Nvidia HEVC
- YV12 Encoder with AVI muxer

[Jan Gruuthuse]

The second step, adding video to this, seems only to be working without hardware acceleration?
- Move slider to end of video and drop the 720p4audioTracks3satá´´á´°.ts onto avidemux canvas.

with hardware hardware acceleration, the images are not showing up in the saved video
without hardware acceleration and display Xvideo (best) the images are shown in the video.

workflow on youtube 2'55 : add png then append video to it

The second step, adding video to this, seems only to be working without hardware acceleration?

Yes, this is expected not to work with hw accel.

I dont think this is related to jpeg or png input
Most probably it is related to very short video + encoder delay

[Jan Gruuthuse]

Apparently this is an separate issue.

however there looks like to be a timeline issue with markers?
While pasting the image A: and B: counters increase each with 00:00:040, causing probably the to short message?

To my understanding:
When loading a video: a time index is created.
Bottom right hand time indicator A: stays @ 00:00:000
While copying one loaded image and multiplicating the loaded image [Ctrl][c]

the faulty? selection caused by A: 00:00:080 B: 00:00:120 is not long enough 'no frame' in selection?

video duration is 00:00:00,040

[Jan Gruuthuse]

Setting [A ] manually to zero, saves now a video correctly.

[Jan Gruuthuse]

Selection should not be set?
Dual use of a variable?
Loaded image only considered 1/2 frame? Perhaps choice when loading image: 1/2 frame (I)nterlaced or 1 frame (P)rogressive?

Your welcome, not always easy to explain from user side. As usually many thanks for all the efforts and improvements.
