In preview, the FLV playback videos are delayed by a several blank keyframes. I have tried exporting the full project/media and this shows up in the mp4 also. I want to say that there are blank keyframes just after the video has played, but I can't determine if this is the case when the video can only be played in Preview Mode. What could be causing the issue and what is it called?
I have tried exporting the full project/media, expecting that the issue was that the Preview was still buffering the FLV playback, but it shows up in the mp4 also.

I am working on a WordPress website and facing a major issues with some of my self hosted videos. I am uploading videos to wordpress media Library and playing them using Easy video player in my posts. There are some video with only audio. I tried those in different browsers and they work fine in UC Mini on Android. Chrome, Edge & Firefox are just playing the audio on both PC & mobile versions.
Please help me get rid of this issue.
Shall be thankful
you can check sample here
your video is encoded as MPEG4 - part 2. this is a really old format. I'd recommend re-encoding the video as mp4 using the h264 codec.
At an hour long - you might also want to consider adaptive bitrate streaming - to allow for different screen sizes and varying network conditions.
i am writing an app that preview then capture video from a Video Device (ex:Cam), i didn't found a solution to take a snapshot during capturing with a ASF format.
so i thought i could take a picture from the preview panel but the background-image didn't contain it, and the image property of is null if i use a Picturebox .
do anyone knew how Directshow use the panel or Picturebox to preview video?
Typical solution for capture with preview is to add a tee (smart tee) and then do writing and presentation on the outputs of that tee respectively. PlayCap DirectShow.NET sample shows how to visualize video feed. Video renderer provides methods to read back last presented video frame, so that you could make a snapshot out of it.
Separate parts of this task have been discussed many times, including here:
Preview a camera in DirectShow and capture a still image - in VB.net
VB.Net Directshow Webcam Snapshot
Capturing pictures from webcam at high resolution while previewing at a lower one using DirectShow.Net

I have a video clip that has some issues on default install of Win7: video plays without sound. The video clip comes from a mobile phone, it's a 3gp (mp4) file format with H264 video and AMR audio.
I wanted to find out what I can do to add playback support for AMR audio on that machine. VLC or klite/ffdshow codec packs are out of the question here. I tried to use AMR dshow decoder from MonoGram but it doesn't solve the problem. When I tried to see the graph in MonoGram graph studio it doesn't show me the graph how win7 at all is able to play the video. Seems like it doesn't use dshow filters/decoders in case of this video clip.
So the questions is: how does it play the clip and how can I extend default os functionality to make my clip playable.
I want to pick video from photo library using imagePickerController.
but there is no video on my simulator. I know how to load images in simulator but don't know how to load video. Please help.
You will have to drag&drop a .mov file to the simulator. Once you do that, you will see the video and you can save it to the camera roll (with one of the buttons displayed in that screen).
But you won't be able to pick the video in the simulator because there is an error while compressing the video.
I have movie clips containing FLV video sequences.
When this FLV plays in a SWF compiled from mxmlc, the video is completely corrupted - all different coloured blocks. If I compile from the IDE the video plays fine.
It's a bit more involved than this:
If I play multiple copies of the same FLV at the same time, they're fine, whereas if I play various FLVs at the same time, they corrupt.
They don't always corrupt on every playthrough - it's not consistent.
If I zoom into the corrupted video, or move the player window, the corrupted image remains intact, i.e. it's not like a screen redrawing error where the corrupted area will often change or clear.
Does anyone know of any Flex compiler options, or SWC authoring strategies to get around this?
