Android开发 m3u8视频流截取第一帧用Imageview显示

解析m3u8视频url第一个切片ts的url

public class M3u8AnalysisUtil {
    private static final OkHttpClient client = new OkHttpClient();

    public static String getFirstTsUrl(String m3u8Url) throws IOException {
        Request request = new Request.Builder()
                .url(m3u8Url)
                .build();
        Response response = client.newCall(request).execute();
        if (!response.isSuccessful()) {
            throw new IOException("Unexpected code " + response);
        }

        String m3u8Content = response.body().string();
        String[] lines = m3u8Content.split("\n");
        for (String line : lines) {
            line = line.trim();
            if (line.endsWith(".ts") && !line.startsWith("#")) {
                if (!line.startsWith("http")) {
                    int lastIndex = m3u8Url.lastIndexOf("/");
                    if (-1 != lastIndex) {
