Hi all! Opened a video file with a variable bitrate - it turned out not very well. Advise what to do to handle such files in the program? I do not want pre-encoding. Video https://yadi.sk/i/pHpGWq4f00yVLA Image https://yadi.sk/i/K9fEyyNnBzT-zQ -- Ugin.
Hi, Sorry to hear you are having trouble. I loaded the vid.mp4 file on my system and it seems to work as it should. This means I don't have a way to debug the problem. If it works here, I can't fix it. I need a way to produce the problem so I can fix it. On my system, the timeline thumbnails are all drawn, but not in your img.png, The view loads and plays the media, and the audio is decoded and plays. The only thing that was unusual was that the framerate was 19.8333, but it plays audio and video synchronously, so it does not seem to cause a problem. The asset info detail menu shows: file path: /tmp/vid.mp4 94650090 bytes info: format: mov,mp4,m4a,3gp,3g2,mj2 1 video stream vid0 (0), id 0x00001b: video1 h264 1920x1080 19.83 pix yuvj420p 745+0 frms 37.56 secs 0:00:37.56 1 audio stream aud0 (1), id 0x015002: audio1-2 aac fltp 48000 0bits 1803236+0 smpl 37.57 secs 0:00:37.57 major_brand=mp42 minor_version=0 compatible_brands=isommp42 creation_time=2019-07-26T13:28:21.000000Z com.android.version=7.0 This loads and plays. The media seems undamaged on my system. The wave display (in img.png) in the main window timeline shows that at least the audio was decoded. This means that the file format and audio codecs probed correctly, and that the audio decoder works even though you cannot hear it. I suspect the sound device or audio driver setup needs attention. Check Settings->Preferences for the *Playback A Audio Out setup. I attached a scrngrab of my playback prefs for comparision. I was not able to get the timeline thumbnails to fail. The usual reason that the timeline redraw is damaged like this is that the media does not support seeking, not all media supports seeking... but in the sample you provided restarts playback at any point on the timeline, so seeking seems to work for this sample. Zooming the timebar (up/dn arrow keys on the timeline) causes new thumbnails to be created correctly (uses seeking) as well. An easy way to check setup changes is to start cinelerra using: CIN_CONFIG=/tmp/bcast5 /<path>/cin and open the media file without reconfiguring anything. This uses all defaults, and not modify your normal .bcast5 config. The Audio Driver selection normaly works well with Alsa "default", but does also work with direct Alsa interfaces (Device: pulldown menu). I have not tried OSS recently, and I do not have any of the other legacy sound boards so I cannot test them. On my system, I can get my "Syba 7.1 Surround Sound #0" running "16 bit", but that takes a kernel mod. It is my experience that it is rare for Alsa to fail. If possible, create a /tmp/bcast5 using the above method, and send a tarball of this directory to me. I can use it to create a more complete setup to retest the problem. gg Attached: vid.png On Mon, Jul 29, 2019 at 3:06 AM <[email protected]> wrote:

Why I did not try to open the file on a clean profile - I do not know. Many thanks for the tip! Also, it turned out to start the sound by changing the device in the program settings. Here is a link to the archive directory /tmp/bcast5: https://yadi.sk/d/CGROQMLY-4uqmg although now everything works for me. Thanks again for the help. Ugin. 29.07.2019 16:49, Good Guy пишет:
