pub struct FfmpegLiveThumbnailCommand { /* private fields */ }Expand description
One-frame capture from a live HLS playlist, used to populate the directory thumbnail for an active channel.
Network reads are bounded so a stalled HLS source can never block the
per-channel capture loop. -rw_timeout is microseconds in FFmpeg; it is
set to 5s, which is well below a typical capture cadence so a hung source
fails the tick and lets the next one run unimpeded.
Implementations§
Source§impl FfmpegLiveThumbnailCommand
impl FfmpegLiveThumbnailCommand
Sourcepub fn new(
ffmpeg_bin: impl Into<String>,
input_url: impl Into<String>,
output_path: impl Into<PathBuf>,
) -> Self
pub fn new( ffmpeg_bin: impl Into<String>, input_url: impl Into<String>, output_path: impl Into<PathBuf>, ) -> Self
Build a live-thumbnail capture command.
Sourcepub fn args(&self) -> Vec<OsString>
pub fn args(&self) -> Vec<OsString>
The exact FFmpeg argument vector this command runs.
The output path is threaded through as its raw OsStr (not a lossy
String) so a non-UTF-8 path reaches Command intact.
Sourcepub fn run(&self) -> Result<u64, MediaError>
pub fn run(&self) -> Result<u64, MediaError>
Run FFmpeg and return the captured file size in bytes.
§Errors
Returns an error when the output directory cannot be created, FFmpeg
exits unsuccessfully, or the output cannot be inspected.
Sourcepub async fn run_with_deadline(
&self,
deadline: Duration,
) -> Result<u64, MediaError>
pub async fn run_with_deadline( &self, deadline: Duration, ) -> Result<u64, MediaError>
Run FFmpeg under an async deadline, killing the child process on
timeout so a hung source can never leak a detached process across
capture ticks.
§Errors
Returns an error when the output directory cannot be created, the child
cannot be spawned, the deadline elapses (after killing the child),
FFmpeg exits unsuccessfully, or the output cannot be inspected.
