Subtitles for AVPlayer/MPMoviePlayerController

阅读更多关于 Subtitles for AVPlayer/MPMoviePlayerController

I am using m3u8 video format for streaming the video and now I need to display subtitles for the same. I searched in Apple Documentation and found that I can achieve this by using the closedCaptionDisplayEnabled property of AVPlayer . I am interested to know what should be the format of subtitles? Will the .srt format do? Also can I achieve the same using MPMoviePlayerController ? Any help is appreciated. Update 10/30/2018: It's worth checking this answer by an Apple engineer (Thanks to @allenlini for pointing it out ). He suggests a solution involving AVAssetResourceLoaderDelegate . I haven't

displaying subtitles for a video in a WPF MediaElement

阅读更多关于 displaying subtitles for a video in a WPF MediaElement

问题 I'm working on a WPF application that displays video clips as part of the workflow. I'm doing this by using MediaElement to play locally hosted (not streamed) AVI files. Works great. However, I was just handed a new requirement to allow the display of subtitles while the clip is playing. I have no idea of the best way to go about this. I'm vaguely aware that WMP has the ability to display separate subtitle files when a clip is playing, but I don't know if WPF supports this? Can I do this

阅读更多关于 Use ffmpeg to add text subtitles

I am trying to add text subtitles to an .mp4 container using ffmpeg: ffmpeg -i input.mp4 -i input.srt -map 0.0 -map 0.1 -map 1.0 output.mp4 When I am trying to run this line, it gives me an error : Nmber of stream maps must match number of output streams. If I try to change the mp4 to mkv (although mp4 supports text subtitles), like this: ffmpeg -i input.mp4 -i input.srt -map 0.0 -map 0.1 -map 1.0 output.mkv It correctly maps the streams, but gives an error : Encoder (codec id 94210) not found for output stream #0.2 When I launch ffmpeg -codecs I can see that srt codec is supported as decoder

I have one figure which contains many subplots. fig = plt.figure(num=None, figsize=(26, 12), dpi=80, facecolor='w', edgecolor='k') fig.canvas.set_window_title('Window Title') # Returns the Axes instance ax = fig.add_subplot(311) ax2 = fig.add_subplot(312) ax3 = fig.add_subplot(313) How do I add titles to the subplots? fig.suptitle adds a title to all graphs and although ax.set_title() exists, the latter does not add any title to my subplots. Thank you for your help. Edit: Corrected typo about set_title() . Thanks Rutger Kassies ax.title.set_text('My Plot Title') seems to work too. fig = plt
