<p>Currently I have the following command,</p> <p>which cuts the video, adds audio and burns subtitle into the video.</p> <pre><code>-ss 00:00:30 -t -i video.mp4 -i audio.wav -vcodec copy -acodec copy -map 0:0 -map 1:0 -vf subtitles=subtitle.srt </code></pre> <p>but I need to crop the video before the subtitle is added. I know it is possible to crop video using the command:</p> <pre><code>-vf crop=405:720 </code></pre> <p>or using</p> <pre><code>-filter:v crop=405:720 </code></pre> <p>but I am unable to use it in conjunction with the above statement. What would be the best approch to get the desribed outcome?</p>

<p>So I have been testing the SRT streaming to use with OBS. so far love it BUT ffplay will not close when the stream ends and try to reconnect. it just stays paused at last frame and the ffplay window stays up</p> <p>my code is here:</p> <pre><code>%ffplay% srt://0.0.0.0:43560?mode=listener&amp;transtype=live&amp;latency=0&amp;recv_buffer_size=0 -window_title &quot;SRT Player 1.0 - Viewer (powered by FFPlay)&quot; -x 720 -y 480 -sync audio -autoexit </code></pre> <p>I have tried using these commands too:</p> <pre><code>connect_timeout=milliseconds linger=seconds timeout=microseconds </code></pre> <p>What I would like to achieve that if stream ends it closes and then starts ffplay over again. I have even used FFMPEG to grab the original and if it finds it to start ffplay like this:</p> <pre><code>%ffmpeg% -hide_banner -loglevel 0 -stats -re -i srt://127.0.0.1:5000?mode=listener -c copy -f mpegts &quot;srt://127.0.0.1:43560?mode=caller&amp;transtype=live&amp;latency=400000&quot; | %ffplay% srt://0.0.0.0:43560?mode=listener&amp;transtype=live&amp;latency=0&amp;recv_buffer_size=0 -window_title &quot;SRTt Player 1.0 - Viewer (powered by FFPlay)&quot; -x 720 -y 480 -sync audio -autoexit -exitonmousedown -autorotate </code></pre> <p>But this fails as well because of stream ends it just sits open.</p>

<p>we need to preview videos with overlayed so-called &quot;safe areas&quot; according to this EBU document: <a href="https://tech.ebu.ch/docs/r/r095.pdf" rel="nofollow noreferrer">SAFE AREAS FOR 16:9 TELEVISION PRODUCTION</a>.</p> <p>Here's the scheme for 1080p resolution: <a href="https://i.sstatic.net/acMUH.png" rel="nofollow noreferrer"><img src="https://i.sstatic.net/acMUH.png" alt="enter image description here" /></a></p> <p>Those consist of three different &quot;zones&quot;, each with the same percentage size-to-the-edge of the video frame for any resolution:</p> <ul> <li><strong>Action Safe Area</strong> (GREEN box): 3.5%</li> <li><strong>Graphics Safe Area</strong> (RED box): 5%</li> <li><strong>4:3 Safe Area</strong> (GREY box): 16.25%</li> </ul> <p>It should be easily achieveable using the <em>drawbox</em> command, but how can be dynamically adapted to any video resolution?</p>

<p>I am using the following command to read a RTSP stream from an IP camera and record it as HLS:</p> <p><code>ffmpeg -i rtsp://&lt;user&gt;:&lt;password&gt;@&lt;ip&gt;:&lt;port&gt; -c:v copy -c:a copy -hls_segment_type mpegts -segment_list_type m3u8 -hls_list_size 5 -hls_wrap 5 -hls_time 5 -hls_flags split_by_time -segment_time_delta 1.00 -start_number 1 -segment_list live -reset_timestamps 1 -movflags faststart live.m3u8</code></p> <p>Everything goes well. However, while I am using ffplay as <code>ffplay -i live.m3u8</code>, it only plays a few first segments. Even VLC does play a few first segments too! What am I missing? shall I change my ffmpeg command or what?</p> <p>Thank you all in advance.</p>

<p>Is there a way to suppress configuration information when starting ffplay? I know I could redirect to /dev/null but I don't want to lose stderr or stdout. Thanks!</p>
