RaspberryPiでMpeg2→Mpeg4へトランスコードする・続3

３回に渡って試行錯誤しながらやってきたが、
やり方がほぼ確立されたので今回で総集編となる。

Step1.準備
　$ git clone https://github.com/dickontoo/omxtx.git
　$ cd omxtx
　$ make
　$ sudo cp /usr/local/bin/ omxtx

Step2.トランスコード src.ts -> out.mp4（Mpeg2:1440x1080→Mpeg4:960x540)
　$ ffmpeg -y -i src.ts -acodec copy dst.aac -vcodec copy -an aaa.m2v
　$ omxtx -x -v -d -r 960x540 aaa.m2v dst.mp4
　$ ffmpeg -y -i dst.aac -i dst.mp4 -vcodec copy -acodec copy out.mp4

これで完成。
処理時間はほぼ録画時間と同じで終わるので非力なCPUなのにがんばってると思う。
でもハードウェアエンコード・デコード特有というのか、OpenMax側で異常データと判断すると
フレーム落ちして画像が乱れてしまう問題がある。
画像を縮小しなければフレーム落ちしないから、続２で見たアスペクト比の設定パラメータが影響してるのかもしれない。。
あとは１６の倍数で割り切れる画面サイズでないといけない可能性のあるので、
画面サイズは、
　256x144　◎エラーなし
　512x288　×フリーズする　768x432
　1024x576
　1280x720

のいずれかになるようにする。



 出力例（最後の方にフレームエラーが多発している。。）

RaspberryPiでMpeg2→Mpeg4へトランスコードする・続２

前回の続き、
http://ivis-mynikki.blogspot.jp/2014/11/rasberry-pimpeg2mpeg4.html

omxtxをmakeするとき、ライブラリが足りないものはaptitudeで調べて ***-devをインストール。
リンカエラーが出たら LIBS=-lavcodec など追加していくとビルドが通る。

テストデータをMP4化してみてchromebookで再生できるかと思ったら再生できなかったが、
出来上がったMP4動画ファイルに音声ファイルを結合すると再生できた。
でも画質が悪い。一昔のVHS映像並。なんでだろう。


ビットレートの設定が反映されてないような気がするので
ソースを見てみる。

まずはMain関数から。
引数を展開して、Init処理から始まる。
 
動画ファイルをオープンして、
 vidindex = av_find_best_stream(ic, AVMEDIA_TYPE_VIDEO, -1, -1,
                NULL, 0);

Mpeg2デコード、Mpeg4エンコード、リサイズ設定して、、
        bcm_host_init();
        OERR(OMX_Init(), ctx.verbose);
        OERR(OMX_GetHandle(&m2, DECNAME, &ctx, &decevents), ctx.verbose);
        OERR(OMX_GetHandle(&m4, ENCNAME, &ctx, &encevents), ctx.verbose);
        OERR(OMX_GetHandle(&resize, RESIZENAME, &ctx, &resizeevents), ctx.verbose);

OpenMAXにパラメータ送信して、
         OERR(OMX_GetParameter(m2, OMX_IndexParamVideoInit, porttype), ctx.verbose);
        if (ctx.verbose) printf("Found %d ports, starting at %d (%x) on decoder\n",
                porttype->nPorts, porttype->nStartPortNumber,
                porttype->nStartPortNumber);
        ctx.decportidx = decportidx = porttype->nStartPortNumber;

        OERR(OMX_GetParameter(resize, OMX_IndexParamImageInit, porttype), ctx.verbose);
        if (ctx.verbose) printf("Found %d ports, starting at %d (%x) on resizer\n",
                porttype->nPorts, porttype->nStartPortNumber,
                porttype->nStartPortNumber);
        ctx.resizeportidx = resizeportidx = porttype->nStartPortNumber;

        OERR(OMX_GetParameter(m4, OMX_IndexParamVideoInit, porttype), ctx.verbose);
        if (ctx.verbose) printf("Found %d ports, starting at %d (%x) on encoder\n",
                porttype->nPorts, porttype->nStartPortNumber,
                porttype->nStartPortNumber);
        ctx.encportidx = encportidx = porttype->nStartPortNumber;
        free(porttype);

        OERR(OMX_SendCommand(m2, OMX_CommandPortDisable, decportidx, NULL), ctx.verbose);
        OERR(OMX_SendCommand(m2, OMX_CommandPortDisable, decportidx+1, NULL), ctx.verbose);
        OERR(OMX_SendCommand(resize, OMX_CommandPortDisable, resizeportidx, NULL), ctx.verbose);
        OERR(OMX_SendCommand(resize, OMX_CommandPortDisable, resizeportidx+1, NULL), ctx.verbose);
        OERR(OMX_SendCommand(m4, OMX_CommandPortDisable, encportidx, NULL), ctx.verbose);
        OERR(OMX_SendCommand(m4, OMX_CommandPortDisable, encportidx+1, NULL), ctx.verbose);

処理開始。
　　　　OERR(OMX_SendCommand(m2, OMX_CommandStateSet, OMX_StateExecuting, NULL), ctx.verbose);

ビットレートの設定が無いなって思ったら、実行処理の中にある
DECTUNNELSETUP内のconfigure関数で行っているようだった。

これであってるのか分からないが。。
１つ気づいたのはデインターレース処理が入ってないなって思ったので、
対応したomxtxが調べてみたらありました。

Dickon hood氏が2013年に対応してくださっていたようだ。
 * (c) 2012, 2013 Dickon Hood
 * Timing fixups by Adam Charrett
 *
 * A trivial OpenMAX transcoder for the Pi.
 *
 * Very much a work-in-progress, and as such is noisy, doesn't produce
 * particularly pretty output, and is probably buggier than a swamp in
 * summer.  Beware of memory leaks.
 *
 * Usage: ./omxtx [-b bitrate] [-r size] [-x] [-d] [-m] input.foo output.mp4

でも今ビルドしたものはArjen氏が改造したもの。
 * (c) 2012 Dickon Hood
 * modified dec 2012 by Arjen V
 * Added resizer functionality
 * Added pixelaspectratio (hardware)
 *
 * A trivial OpenMAX transcoder for the Pi.
 *
 * Very much a work-in-progress, and as such is noisy, doesn't produce
 * particularly pretty output, and is probably buggier than a swamp in

 *
 * Usage: ./omxtx [-v] [-b bitrate] [-s WxH] input.foo output.m4v

追加内容を見ると、
＜Deckon氏＞
    pixaspect->nPortIndex = PORT_ENC+1;
    pixaspect->nX = 64;
    pixaspect->nY = 45;
//    OERR(OMX_SetParameter(dec, OMX_IndexParamBrcmPixelAspectRatio, pixaspect));

 ＜Arien氏＞
       pixaspect->nPortIndex = encportidx+1;
        pixaspect->nX = 118;
        pixaspect->nY = 81;
        OERR(OMX_SetConfig(m4, OMX_IndexParamBrcmPixelAspectRatio, pixaspect), ctx->verbose);
        free(pixaspect);

 少し設定値が違うようだけど、Deckon氏の早く気づいておけばよかった。。

今日はここまで。


次回は最新版のomxtxでビットレートの設定が正しくなっているか、

またはデコード・エンコードの仕方を見直し？を行う。
